Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either costly or have limited sensitivity. In a recent study, ...

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 ...

Bioengineers have developed biocompatible generators that create electrical pulses when compressed by body motions. The generators are made up of self-assembling "piezoelectric wafers" which can be ...
