Correct Answer - Option 4 : Acceleration
Transducers:
Any device which is able to convert one form of energy into another form is called a transducer.
Piezoelectric transducer:
It is a device that uses the piezoelectric effect to measure changes in acceleration, pressure, strain, or force by converting this energy into an electrical charge.
Piezoelectric Effect:
The EMF develops because of the displacement of the charges. The effect is changeable, i.e. if the varying potential applies to a piezoelectric transducer, it will change the dimension of the material or deform it. This effect is known as the piezoelectric effect.

Temperature transducers (e.g. a thermocouple)
- Pressure transducers (e.g. a diaphragm)
- Displacement transducers (e.g. LVDT)
