The emergence of nanogenerators is not far off

Scientists from the Georgia Institute of Technology are engaged in the development of a nanogenerator that generates energy from blood flow, pulsing veins and heartbeat.

At the moment, scientists have already managed to create a nanodevice, which, when immersed in a biological “fluid” medium, is able to generate electricity by absorbing ultrasonic waves. According to researchers, the device will be suitable for use in implants and as a source of energy for the so-called "personal electronics."
