Explanation:
Detailed explanation-1: -Output devices allow a system to present information back into the ‘real’ world. Examples can be seen everywhere, from car indicators to doorbell buzzers or information displays.
Detailed explanation-2: -When a voltage is applied across the two electrodes, the piezoelectric material mechanically deforms due to the applied voltage.
