“For the living room, a sensual green with temperature and motion sensors.” In the future, you may be able to order that or something similar for your smart home. Sometime soon, new types of sensors could become a reality on your four walls.Science or fiction? More and more often, we find ourselves having to answer that question with science. That also applies to tiny new sensors that—hidden in wall paint—could make smart homes even smarter. On the one hand, they would have to be very, very small, and on the other, they would have to work without a battery. Researchers at the University of Eindhoven have already found an elegant solution. Their tiny temperature sensor gets its energy from the same radio waves that it uses to transmit its measuring results. First it receives radio waves from a special router via an antenna and stores it as energy. Starting at a certain energy level, it then measures the temperature and sends the results to the router. And it does so at exactly the same frequency that was chosen in advance for the measured temperature value. The router then uses the information to calculate the actual temperature. The walls have earsThe range of the tiny sensor, which measures just two square millimeters in size and weighs just 1.6 milligrams, is limited to 2.5 centimeters. But researchers hope to reach one meter during the next year. They are aiming for up to five meters in the future. Because the sensor also works under a coat of paint, pavement or concrete, there are only a few restrictions to its applications. For example, in smart homes or production environments, it could be “painted” onto the building’s walls with paint. And not just as a “thermometer”. The technology can also be used for sensors that measure motion, light and moisture. Right now the sensor stems from a 65-nm CMOS process. Produced in mass, the cost of production should come in at around 30 cents. Ref.KY45-LM35DTKY45-AMB2402

Three fingers on a new soft robotic gripper each have specialized sensors that can estimate the size and shape of an object accurately enough to identify it from a set of multiple items.  Robots have many strong suits, but delicacy traditionally hasn't been one of them. Rigid limbs and digits make it difficult for them to grasp, hold, and manipulate a range of everyday objects without dropping or crushing them. Recently, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have discovered that the solution may be to turn to a substance more commonly associated with new buildings and Silly Putty: silicone. At a conference this month, researchers from CSAIL Director Daniela Rus' Distributed Robotics Lab demonstrated a 3-D-printed robotic hand made out of silicone rubber that can lift and handle objects as delicate as an egg and as thin as a compact disc. Just as impressively, its three fingers have special sensors that can estimate the size and shape of an object accurately enough to identify it from a set of multiple items. "Robots are often limited in what they can do because of how hard it is to interact with objects of different sizes and materials," Rus says. "Grasping is an important step in being able to do useful tasks; with this work we set out to develop both the soft hands and the supporting control and planning systems that make dynamic grasping possible." The paper, which was co-written by Rus and graduate student Bianca Homberg, PhD candidate Robert Katzschmann, and postdoc Mehmet Dogar, will be presented at this month's International Conference on Intelligent Robots and Systems. The hard science of soft robots The gripper, which can also pick up such items as a tennis ball, a Rubik's cube and a Beanie Baby, is part of a larger body of work out of Rus' lab at CSAIL aimed at showing the value of so-called "soft robots" made of unconventional materials such as silicone, paper, and fiber. Researchers say that soft robots have a number of advantages over "hard" robots, including the ability to handle irregularly-shaped objects, squeeze into tight spaces, and readily recover from collisions. "A robot with rigid hands will have much more trouble with tasks like picking up an object," Homberg says. "This is because it has to have a good model of the object and spend a lot of time thinking about precisely how it will perform the grasp." Soft robots represent an intriguing new alternative. However, one downside to their extra flexibility (or "compliance") is that they often have difficulty accurately measuring where an object is, or even if they have successfully picked it up at all. That's where the CSAIL team's "bend sensors" come in. When the gripper hones in an object, the fingers send back location data based on their curvature. Using this data, the robot can pick up an unknown object and compare it to the existing clusters of data points that represent past objects. With just three data points from a single grasp, the robot's algorithms can distinguish between objects as similar in size as a cup and a lemonade bottle. "As a human, if you're blindfolded and you pick something up, you can feel it and still understand what it is," says Katzschmann. "We want to develop a similar skill in robots—essentially, giving them 'sight' without them actually being able to see." The team is hopeful that, with further sensor advances, the system could eventually identify dozens of distinct objects, and be programmed to interact with them differently depending on their size, shape, and function. How it works（“We want to ... give robots‘sight’ without them actually being able to see,” says MIT grad student Robert Katzschmann. ） Researchers control the gripper via a series of pistons that push pressurized air through the silicone fingers. The pistons cause little bubbles to expand in the fingers, spurring them to stretch and bend. The hand can grip using two types of grasps: "enveloping grasps," where the object is entirely contained within the gripper, and "pinch grasps," where the object is held by the tips of the fingers. Outfitted for the popular Baxter manufacturing robot, the gripper significantly outperformed Baxter's default gripper, which was unable to pick up a CD or piece of paper and was prone to completely crushing items like a soda can. Like Rus' previous robotic arm, the fingers are made of silicone rubber, which was chosen because of its qualities of being both relatively stiff, but also flexible enough to expand with the pressure from the pistons. Meanwhile, the gripper's interface and exterior finger-molds are 3-D-printed, which means the system will work on virtually any robotic platform. In the future, Rus says the team plans to put more time into improving and adding more sensors that will allow the gripper to identify a wider variety of objects. "If we want robots in human-centered environments, they need to be more adaptive and able to interact with objects whose shape and placement are not precisely known," Rus says. "Our dream is to develop a robot that, like a human, can approach an unknown object, big or small, determine its approximate shape and size, and figure out how to interface with it in one seamless motion." Ref.KY45-TSL1401CLKY45-11242-11

(A test sample comprised of a thermal chip, a heat spreader and a microcooler demonstrates the efficiency of diamond for removing heat from hotspots in semiconductor electronics.) Powerful electronic components can get very hot. When many components are combined into a single semiconductor chip, heating can become a real problem. An overheating electronic component wastes energy and is at risk of behaving unpredictably or failing altogether. Consequently, thermal management is a vital design consideration. This becomes particularly important in devices made from gallium nitride. "Gallium nitride is capable of handling high voltages, and can enable higher power capability and very large bandwidth," says Yong Han from the A*STAR Institute of Microelectronics. "But in a gallium nitride transistor chip, the heat concentrates on tiny areas, forming several hotspots." This exacerbates the heating problem. Han and co-workers demonstrate both experimentally and numerically that a layer of diamond can spread heat and improve the thermal performance of gallium nitride devices. The researchers created a thermal test chip that contained eight tiny hotspots, each 0.45 by 0.3 millimeters in size, to generate the heat created in actual devices. They bonded this chip to a layer of high quality diamond fabricated using a technique called chemical vapor deposition. The diamond heat spreader and test chip were connected using a thermal compression bonding process. This was then connected to a microcooler, a device consisting of a series of micrometer-wide channels and a micro-jet impingement array. Water impinges on the heat source wall, and then passes through the micro-channels to remove the heat and keep the structure cool. Han and the team tried their device by generating 10–120 Watts of heating power in test chips of 100 and 200-micrometer thickness. To dissipate the heating power, the diamond heat spreading layer and microcooler helped maintain the structure at a temperature below 160 degrees Celsius. In fact, the maximum chip temperature was 27.3 per cent lower than another device using copper as the heat spreading layer, and over 40 per cent lower than in a device with no spreading layer. The experimental results were further confirmed by thermal simulations. The simulations also indicated that the performance could be improved further by increasing the thickness of the diamond layer, and that good bonding quality between the gallium nitride chip and the diamond heat spreader was crucial to obtain the best performance. "We next hope to develop a novel micro-fluid cooler of higher and more uniform cooling capability, and to achieve thermal management using a diamond layer of high thermal conductivity near an electronic gate," says Han. Ref.KY56-MJL4302AKY56-PZTA06KY56-FZT958TA  

The world's most precise clock has been fine-tuned to boost radar and GPS capabilities.The Cryogenic Sapphire Oscillator, or Sapphire Clock, has been enhanced by researchers from the University of Adelaide in South Australia to achieve near attosecond capability. The oscillator is 10-1000 times more stable than competing technology and allows users to take ultra-high precision measurements to improve the performance of electronic systems. Increased time precision is an integral part of radar technology and quantum computing, which have previously relied on the stability of quartz oscillators as well as atomic clocks such as the Hydrogen Maser. Atomic clocks are the gold-standard in time keeping for long-term stability over months and years. However, electronic systems need short-term stability over a second to control today's devices. The new Sapphire Clock has a short-term stability of better than 1x10-15, which is equivalent to only losing or gaining one second every 40 million years, 100 times better than commercial atomic clocks over a second. The original Sapphire Clock was developed by Professor Andre Luiten in 1989 in Western Australia before the team moved to South Australia to continue developing the device at the University of Adelaide. Lead researcher Martin O'Connor said the development group was in the process of modifying the device to meet the needs of various industries including defence, quantum computing and radio astronomy. The 100cm x 40cm x 40cm clock uses the natural resonance frequency of a synthetic sapphire crystal to maintain a steady oscillator signal.Associate Professor O'Connor said the machine could be reduced to 60 per cent of its size without losing much of its capability."Our technology is so far ahead of the game, it is now the time to transfer it into a commercial product," he said. "We can now tailor the oscillator to the application of our customers by reducing its size, weight and power consumption but it is still beyond current electronic systems." The Sapphire Clock, also known as a microwave oscillator, has a 5 cm cylinder-shaped crystal that is cooled to -269C. Microwave radiation is constantly propagating around the crystal with a natural resonance. The concept was first discovered by Lord Rayleigh in 1878 when he could hear someone whispering far away on the other side of the church dome at St Paul's Cathedral. The clock then uses small probes to pick up the faint resonance and amplifies it back to produce a pure frequency with near attosecond performance."An atomic clock uses an electronic transition between two energy levels of an atom as a frequency standard," Associate Professor O'Connor said."The atomic clock is what is commonly used in GPS satellites and in other quantum computing and astronomy applications but our clock is set to disrupt these current applications."  The lab-based version already has an existing customer in the Defence Science and Technology Group (DST Group) in Adelaide, but Associate Professor O'Connor said the research group was also looking for more clients and was in discussion with a number of different industry groups. The research group is taking part in the Commonwealth Scientific and Industrial Research Organisation's (CSIRO's) On Prime pre-accelerator program, which helps teams identify customer segments and build business plans. Ref.KY45-E3X-DA6KY163-TX179

 There are a number of hot new technologies on the forefront of online and offline retail including machine learning, the Internet of Things (IoT) and Blockchain, the information-sharing technology behind Bitcoin.We have written a bit lately about machine learning because it perhaps has the highest “world-changing” potential. But the IoT – especially when it comes to radio frequency identification (RFID) – also has huge potential to transform any retail operation.RFID has been around for many years and has been adopted by a range of retailers including Walmart, Macy’s and Amazon. The way it works is simply that each product is given a radio frequency ID tag and that tag has its own unique magnetic signature. That signature is picked up by a receiver or “RFID reader” that not only records the unique ID, but also the location of the tagged product. RFID is also the same technology that you see on new tap-and-go credit cards.  Because the tags are read magnetically, it is a more efficient system than a typical visual scanning system because the tag and the reader do not need to be line-of-site to communicate.  Therefore, the immediate benefit for an RFID-based system is that a typical retailer can reduce the time required to take a typical physical inventory by something like 90 percent.  In other words, if it took 3 days to take an inventory using barcode scanning, that same inventory would take 45 minutes using RFID. RFID also increases accuracy substantially. Usually manual-scanned physical inventory has a 4 percent inaccuracy rate.  And that number is compounded throughout the year, so cycle counts done throughout the fiscal year can reach more than 60 percent inaccuracy by the holiday selling season. Conversely, RFID typically has less than a 0.5 percent inaccuracy rate, meaning that inventory is much more accurate throughout the year.Here are some more innovative uses for RFID: Adhering To The Master Merchandising Plan Most chain retail stores have their own planogram, designating where each product should go in the store. However, the more stores that a retail chain operates, the harder it is to get each store to execute the central buyer’s merchandise plan precisely. With enough readers placed in strategic locations throughout the store, most merchandise can be tracked within a very small area. This means that the central buyer can get a report of all of the misplaced merchandise in each store. This means that if a cellphone accessory is mistakenly placed in the video game section, it will show up on a report and can be immediately remedied in the field.  In addition, oftentimes products remain in the stockroom when in fact they should be out on the floor. A solid RFID system will be able to detect whether or not items are still in the backroom, where they probably won’t sell well. Inventory Accuracy – Improving Click & CollectMost retailers have an omnichannel strategy – meaning that customers can buy online and then pick up their orders in the store. Of course, this kind of click-and-collect strategy is predicated upon the accuracy of the inventory count in each store.  In other words, if the system says that there are two units of a certain SKU in a particular store, but actually there is an inaccuracy and there are zero, they will deliver a terrible customer experience when the customer shows up at the store only to find out that the product is not there. The far better accuracy of RFID will allow retailers to have a much greater confidence level that the product is actually in the place that the system says it is.  Understanding the Store’s Hot SpotsAnother benefit of RFID is that there is a record of where products are displayed in a store. And that record can be overlaid with sales data so that we understand what specific displays and traffic areas within the store deliver the most sales. Of course, different spots within a particular store may work better with some products than they do with others.  RFID technology can also help determine the best possible scenario when considering the SKU type, store type and display area. Fast & Accurate CheckoutOne of the most customer-facing use cases for RFID is being able to pay for the products much more quickly than ever before. With RFID, the cashier does not even need to take the products out of the customer’s basket in order ring them up in the system. The ability to skip the manual scanning process entirely makes a radical difference in wait times, especially during peak periods. In addition, RFID capability at checkout greatly reduces the cash reconciliation error at the register.  Detecting Fake Goods: A product’s legitimate manufacturer can embed an RFID tag into the product in a hidden place, allowing a reseller to scan for the signal to prove that the product is authentic. The trickier issue is whether or not the actual RFID tag can be forged, but that is fodder for another discussion. There are more and more companies that can deliver a range of RFID-related products and services, from hardware to full-blown systems.Kynix is one of them.  Ref. KY78-A4650KY78-B82450A2364A
