  2. Tonpilz - Wikipedia

    en.wikipedia.org/wiki/Tonpilz

    The term tonpilz or "acoustic mushroom" may refer to a certain type of underwater electro-acoustic transducer. By sandwiching active (i.e. piezoelectric or magnetostrictive) materials between a light, stiff radiating head mass and a heavy tail mass, the transducer can effectively operate as either a projector (source) or a hydrophone (underwater acoustic receiver).

  3. IEEE 1451 - Wikipedia

    en.wikipedia.org/wiki/IEEE_1451

    IEEE 1451 is a set of smart transducer interface standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society's Sensor Technology Technical Committee describing a set of open, common, network-independent communication interfaces for connecting transducers (sensors or actuators) to microprocessors, instrumentation systems, and ...

  4. Surface acoustic wave sensor - Wikipedia

    en.wikipedia.org/wiki/Surface_acoustic_wave_sensor

    Surface acoustic wave sensors are a class of microelectromechanical systems (MEMS) which rely on the modulation of surface acoustic waves to sense a physical phenomenon. The sensor transduces an input electrical signal into a mechanical wave which, unlike an electrical signal, can be easily influenced by physical phenomena.

  5. Electromagnetic acoustic transducer - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_acoustic...

    An electromagnetic acoustic transducer (EMAT) is a transducer for non-contact acoustic wave generation and reception in conducting materials. Its effect is based on electromagnetic mechanisms, which do not need direct coupling with the surface of the material.

  6. Optoelectronics - Wikipedia

    en.wikipedia.org/wiki/Optoelectronics

    Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. [ 1 ] Electro-optics is often erroneously used as a synonym, but is a wider branch of physics that concerns all interactions between light and electric fields , whether or not they form part of an ...

  7. Piezoelectric sensor - Wikipedia

    en.wikipedia.org/wiki/Piezoelectric_sensor

    A piezoelectric transducer can be modeled as a voltage source with a filter. The voltage V at the source is directly proportional to the applied force, pressure, or strain. [ 11 ] The output signal is related to this mechanical force as if it had passed through the filter, which gives the transducer a very high and frequency-dependent output ...
