Sentences with phrase «piezoelectric materials generate»

The Greek word piezein means «to squeeze or press,» and piezoelectric materials generate a charge when squeezed or deformed or smashed — like smashing two rocks together to produce a flash.

Not exact matches

This new tag uses a flexible strip containing piezoelectric materials, which generate electricity through physical movement.

By fabricating piezoelectric materials into cantilevers that resemble a diving board, these devices can oscillate from ambient vibrations and generate electricity.

The piezoelectric effect allows a material to generate an electrical voltage when it is exposed to pressure or stretching.

The new materials, which generate an electric field when squeezed, copy the crystal structure of conventional piezoelectric materials but use bismuth instead of lead.

Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds of other devices.

Piezoelectric materials can generate electricity from a mechanical force; conversely, they also can generate a mechanical strain from an applied electrical field.

In certain materials, piezoelectrics, which expand or contract when applying a voltage, SAWs can be generated through oscillating electric fields.

Abstract: Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: think of lighters that spark when you press a switch, but also microphones, sensors, motors and all kinds of other devices.

We've covered plenty of so - called human - powered devices on TreeHugger and they've all fallen into two categories: friction - powered (triboelectric) devices that harness the energy created from two materials rubbing together and piezoelectric devices that feature crystals that generate energy from being compressed or bent.
