Researchers at the University of Washington's Sensing Laboratory created WISP, a wireless identification and sensing platform. It is learned that WISP combines a sensor with a compute chip, which allows it to operate without a battery or link power cord. It mainly absorbs the radio waves emitted by an RFID reader, that is, the common anti-theft technology in retail stores and converts the radio waves into electric current. No coin-sized WISP wireless identification and sensing platform It is reported that, WISP and Fitbit processors, have a similar clock speed and functionality, including embedded accelerometers and temperature sensors. AaronParks, a researcher at the University of Washington's Sensing Laboratory, said WISP can track sensory data to communicate with the outside world and do some basic information processing. It does this by backscattering wireless signals, Parks said, adding the equivalent of playing the Morse code with lights. Surprisingly, Parks said the technology is pretty fast. Its bandwidth is similar to Bluetooth low-power mode, a wireless charging technology that supports most Bluetooth speakers and wireless headsets. This gives WISP this new feature, thanks to a team of collaborators at Delft University: It now has the ability to rewrite the code wirelessly. So, for example, a fitness tracker using WISP, you can now download new tracking features without having to connect it to any device, or fix it with updates. It's amazing, nobody ever did it before. Batteryless computer chip WISP WISP is not the only batteryless computer chip. Parks said there are other sensors that do not need batteries, absorbing any energy they can find, including passing television waves, cell towers and more. But now, these battery-less computers are slow and far from programmable. By combining WISP and RFID readers, Parks said they have been able to make 10x faster battery-less computers. What can these batteryless computers do? Parks said it is still far from charging the iPhone and laptop with radio waves. However, the area where WISP is currently available is building. Embedded in the reinforced concrete structure of these sensors, inspectors can detect whether the building received damage in the earthquake. Parks also said that battery-less computers can also be used in implantable devices to monitor the patient's health. In addition, the field of agriculture is also interested in WISP computers, and its ability to monitor thousands of plants simultaneously can be of great value. There are many batteryless consumer applications, such as fitness bracelets. Parks said you can even put battery-less computers in your smartphone and send emergency messages when your device is dead. However, the ultimate appeal of WISP and other battery-less computers is in the Internet of Things that will make the device smarter. Epoxy Curing Agents & Accelerators
