Piezoelectric Effect vs. Piezoresistive Effect -
The word “piezo” is derived from piezein, which is Greek for physical pressure in one form or another. Piezo devices, which come in piezoelectric or piezoresistive varieties, are activated through some form of physical pressure. The effects of such pressure depend on the type of device in question. So, what are piezo devices used […]
