It’s official - technology can now use us to power itself. And we’re not even mad about it.
Developed by researchers from the National University of Singapore, this tiny, flexible patch can harvest static electricity from your movements, and use that energy to power small electronic devices - think a Fitbit or an iWatch.
The device is so resourceful that a stamp-sized patch of it can generate 7.5 V of electric potential simply from you talking or flexing your fist. If you tap it, it can generate a maximum of 90 V of open circuit voltage and 0.8 mW - enough power to light up 12 commercial LEDs, as Prachi Patel reports for IEEE Spectrum.
