Yet another approach is to use piezoelectric crystals, tiny pieces of quartz that vibrate when an electric current goes through them.

The inverse effect uses a voltage applied to a piezoelectric crystal to bend it in a desired direction.

Very simple single-action stepping motors can be made with piezoelectric crystals.

He pioneered the use of laboratory grown piezoelectric crystals, which were quite costly at that time.

To absorb the energy produced by dancers, piezoelectric crystals are used.

They consist of a piezoelectric crystal with electrodes attached to each side, glued to a light diaphragm.

A device that used piezoelectric crystals, which produce electricity when bent, was quiet and cut the power burden.

The emission is generated on piezoelectric crystals by the piezoelectric effect.

Examples are a piezoelectric crystal or a small diaphragm whose movement changes a capacitance, but the choice of devices is quite wide.

We used, piezoelectric crystals as pressure detectors in the muscle piles.
