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.
Working mechanism for piezoelectric devices with one end of the piezoelectric material is fixed. The induced piezopotential distribution is similar to the applied gate voltage in a traditional field-effect transistor, as shown in (b).
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 ...
A buzzer or beeper is an audio signaling device, [1] which may be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and beepers include alarm devices, timers, train and confirmation of user input such as a mouse click or keystroke.
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".

PCB Piezotronics is a manufacturer of piezoelectric sensors.. The name "PCB" is abbreviation for "PicoCoulomB" which is technical terminology defining an electrical charge of the type generated by the piezoelectric sensors they manufacture.
To initialize the inchworm motor the clutching piezo closest to the direction of desired motion (which then becomes the forward clutch piezo) is electrified first then the six-step cycle begins as follows (see Figure 2.): Step 1. Extension of the lateral piezo. Step 2. Extension of the aft clutch piezo. Step 3. Relaxation of the forward clutch ...
Piezoelectric balance presented by Pierre Curie to Lord Kelvin, Hunterian Museum, Glasgow. Piezoelectricity (/ ˌ p iː z oʊ-, ˌ p iː t s oʊ-, p aɪ ˌ iː z oʊ-/, US: / p i ˌ eɪ z oʊ-, p i ˌ eɪ t s oʊ-/) [1] is the electric charge that accumulates in certain solid materials—such as crystals, certain ceramics, and biological matter such as bone, DNA, and various proteins—in ...
