Piezoelectric Piezoelectric materials generate a small electric charge when they are put under stress. Both tension and compression stress alter the structure of the material, producing micro-volts of charge that can be siphoned off to power equipment. By creating multiple separate ribbons of a piezoelectric material with desirable properties, something of a bank charge battery can be produced, where each ribbon generates an independent voltage, which then stack.

 Ongoing research into potential piezoelectric power sources for smart prosthetics turned up a powerful - and deadly - candidate in a polymer that is already used for many cosmetic implants. silicon polymer is a fantastic source of energy when squeezed. However, it also damages the organic cells around it each time this occurs.
 A different paradigm in power generation for implants and prosthetics, combines electrical generation and storage in a single thin three-layer flexible ribbon. Piezoelectric in nature, it builds long-term storage into the electrical ggeneration process. No other battery or powersource required.
