Q: What is transducer? Discuss some application of transducer.
A: A transducer is a device that converts one type of energy to another. Energy types include (but are not limited to) electrical, mechanical, electromagnetic (including light), chemical, acoustic or thermal energy. While the term transducer commonly implies the use of a sensor/detector, any device which converts energy can be considered a transducer.
Some application of transducer are:-
Antenna – converts electromagnetic waves into electric current and vice versa
Cathode ray tube (CRT) – converts electrical signals into visual form
Fluorescent lamp, light bulb – converts electrical power into visible light
- Magnetic cartridge – converts motion into electrical form
- Electroactive polymers
Rotary motor, linear motor
- Vibration powered generator
