Piezoelectric accelerometers are used in many different industries, environments, and applications - all typically requiring measurement of short duration impulses. Piezoelectric measuring devices are widely used today in the laboratory, on the production floor, and as original equipment for measuring and recording dynamic changes in mechanical ...
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. For accelerometers, a seismic mass is attached to the crystal
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 ...
Modally-Tuned* Impulse Hammers won the IR-100 Award as one of the top 100 technical developments for 1983. The 128-channel Data Harvester was invented in 1984 to provide sensor power and speed modal analysis by offering automatic bank switching capability. In 1986, PCB developed the first commercial quartz shear-structured ICP® accelerometer.

The introduced piezoelectric field is perpendicular to electron transport direction, just like applying a gate voltage in the traditional field-effect transistor. Thus the electron transport properties will also be changed. [10] The materials for piezotronics should be piezoelectric semiconductors, [10] such as ZnO, GaN and InN.
