Fish scales extracted from food waste have been used to build tiny generators that can convert mechanical energy, such as a touch or sound vibrations, to electrical energy. The work was done by ...

Drums! You hit them, and they vibrate. It’s kind of fun. Piezoelectric elements can create electric current when they vibrate. [Will Dana] put two and two together to try and charge his phone on his ...

Isreali engineers are about to begin testing a 100 metre stretch of roadway embedded with a network of Piezo Electric Generators (IPEG™). The piezoelectric effect converts mechanical strain into ...

Could piezoelectrics soon power your on-bike electronics? As the energy required to power on-bike devices, such as LED lights and GPS computers, has decreased, the potential to employ novel, discreet ...

Achieving so-called zero-power sensors will require harvesting energy from sources in the environment. After narrowing down one’s options to available sources, the next criteria will be the amount of ...
