Integrated Electronics Piezo-Electric (IEPE) characterises a technical standard for piezoelectric sensors which contain built-in impedance conversion electronics. IEPE sensors are used to measure acceleration, force or pressure. Measurement microphones also apply the IEPE standard. Other proprietary names for the same principle are ICP, CCLD ...
Metal disks with piezo material, used in buzzers or as contact microphones Piezoelectric technology can measure various physical quantities, most commonly pressure and acceleration. For pressure sensors , a thin membrane and a massive base is used, ensuring that an applied pressure specifically loads the elements in one direction.
Lubrication-free performance is important for cryogenics, where traditional lubricants may freeze, and for vacuum applications, where lubricants could outgas or trap atmospheric gasses. Piezoelectric actuators can also be made with nonmagnetic materials, which allows their use in MRI machine .
A description of how a piezoelectric accelerometer works in theory. A piezoelectric accelerometer is an accelerometer that employs the piezoelectric effect of certain materials to measure dynamic changes in mechanical variables (e.g., acceleration, vibration, and mechanical shock).
Tinkercad is a free-of-charge, online 3D modeling program that runs in a web browser. [1] Since it became available in 2011 it has become a popular platform for creating models for 3D printing as well as an entry-level introduction to constructive solid geometry in schools.
Insides of a slip-stick piezoelectric motor. Two piezoelectric crystals are visible that provide the mechanical torque. [1]A piezoelectric motor or piezo motor is a type of electric motor based on the change in shape of a piezoelectric material when an electric field is applied, as a consequence of the converse piezoelectric effect.
A piezo switch is an electrical switch based on the piezoelectric effect. The charge generated by the piezoelectric element in the switch is typically used to turn on an integrated semiconductor device such as a field effect transistor (FET), causing the switch assembly's output to be active, or "on".

The following table lists the following properties for piezoelectric materials The piezoelectric coefficients (d 33, d 31, d 15 etc.) measure the strain induced by an applied voltage (expressed as meters per volt).
