Battery-free microcomputer

Power for the fingertip-sized computer is converted from radio waves, allowing it to operate without batteries.

The Sensor Lab research team at the University of Washington (USA) and Delft University of Technology (Netherlands) has successfully developed a digital device that runs without batteries or any external power source. The product, abbreviated as WISP, will absorb radio waves in space and convert them into electricity.

The WISP computer model is capable of operating without batteries or external power sources.

WISP is not designed to compete with the chips in computers or smartphones. However, its processing power is enough to run sensors and transmit data, which can be used for smart wearable devices such as smartwatches, health bands...

The success of this research promises to open up many new directions in the era of the Internet of Things (IoT). The energy consumed by WISP is even lower than Bluetooth LE, which is currently used on many devices.

Another application of WISP is integration into smartphones. This part can help the device make emergency calls even when the battery is dead.
