Question: Ways to use piezoelectric material?

Answer: There is a wide variety of applications for piezoelectric materials. They are commonly used as actuators, sensors, ignition sources, and motors. For example, automatic grill lighters use a piezoelectric material like quartz to produce a high voltage combined with a spark gap to ignite the gas. Some microphones and instrument microphones use the sound vibrations in combination with piezoelectric materials to produce electrical signals to use in amplifiers and other devices. Additional and somewhat futuristic uses include noise or vibration canceling. A voltage applied to a piezoelectric material regulated by sensors can cancel out vibrations by essentially “bending against” the vibration resulting in a uniform and unchanging material. Piezoelectrics are even be used in the medical field to treat things like infertility.
