As seen, the pyroelectric has somewhat limited use. However, it is a rather important type of material, due to the position it holds between piezoelectrics and ferroelectrics. It must also be considered that while it does not have a wide range of uses, its use in the motion detector (see the ‘Infrared Detection’ section) is very common, and as such it can be considered important to understand it.
