A piezoelectric material is one which changes shape when an electric field is applied.
Another common piezoelectric material is quartz, which has also been used in mechanical filters.
The use of piezoelectric materials to harvest power has already become popular.
A piezoelectric material gives off electrical energy when you apply physical stress to it.
A true piezoelectric material will also convert electricity into physical movement.
These sensors are commonly manufactured out of piezoelectric materials such as quartz.
In piezoelectric materials, mechanical expansion occurs due to applied bias.
A static force will result in a fixed amount of charges on the piezoelectric material.
It is a piezoelectric material for microphones and other transducers.
Where the wires joined were transistor-like things and strips of piezoelectric materials.
