Batteries are Not Required The Tiny Computer runs Based on Radio Waves

Researchers from UW researchers University of Washington (UW) have come up with a new kind of computer that gets its power from no battery or other source, but rather by capturing radio waves and transforms into electricity.

Also known in the industry as Wireless Identification and Sensing Platform (WISP) This new technology results from the blend of sensor technology and computing that utilize Radio Frequency Identification (RFID) reader to collect radio waves that surround it to convert them into electrical power.

Although WISP does not have the similar processing capabilities of superior computers on the market today however, it has enough power to power its sensors in the onboard unit and transfer data similar to other wearable devices of a small size.

Researchers believe that this new technology is able to be applied to further develop the Internet of Things (IoT). WISP may enable the creation of devices that require less maintenance than devices that have low-energy Bluetooth sensors.

The battery-free computer is able to be used to design sensors that can monitor the strength of buildings in the event an event of natural catastrophe occurs. Agriculture researchers can also utilize WISP to monitor the development of fields and crops.

Another use for this Wireless Identification and Sensing Platform is an alternative calling module for phones, so users can utilize them in the case of power failure or when their battery is out.

The UW team collaborated closely with colleagues from and at the Delft University of Technology in The Netherlands to provide WISP with wireless programming capabilities. The resultant Wisent protocol lets the battery-free computer be reprogrammed with the radio waves that it receives.

“Our goal is to create completely wirelessly reprogrammable battery-less software-defined computers, wherever and whenever we’d like,” TU Delft Assistant Professor Przemyslaw Pawelczak told the TU Delft News.

The researchers haven’t revealed any details about when the WISP system will become made available to the public , or what price it is likely to cost.
