Microcomputers that run without batteries.

The power for this tiny, fingertip-sized computer is converted from radio waves, allowing it to operate without a battery.

A research team from the Sensor Lab 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, absorbs radio waves in space and converts them into electrical energy.

The WISP computer model is capable of operating without a battery or external power source.

WISPs are not designed to compete with chips found in computers or smartphones. However, their processing power is sufficient to run sensors and transmit data, making them suitable for use in smart wearable devices such as smartwatches and fitness trackers.

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

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