Question:
Piezoelectric transducers are:
Piezoelectric transducers are:
Show Hint
Always remember: Piezoelectric materials can both sense (active) and actuate (inverse), making them dual-role transducers.
Updated On: Jun 24, 2025
- passive transducers
- active transducers
- inverse transducers
- both active and inverse transducers
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Piezoelectric transducers utilize the piezoelectric effect to convert mechanical stress into electrical voltage and vice versa.
They serve as active transducers because they generate electric signals without needing an external power source.
At the same time, they are also capable of working in reverse — applying an electric field to induce mechanical deformation — which makes them inverse transducers.
Thus, piezoelectric devices operate in both directions and serve both roles.
