Inverse Piezoelectric Effect and Ultrasound
What is it?
The inverse piezoelectric effect is the mechanical deformation of a piezoelectric material when an electric field or potential difference is applied.
In simple words
- Alternating voltage makes the crystal vibrate and produce ultrasound.
Recommended for Class 12
Full school-level explanation
The inverse piezoelectric effect is the mechanical deformation of a piezoelectric material when an electric field or potential difference is applied.
Transmission
The inverse effect reverses the basic conversion of the direct piezoelectric effect. Electrical signal → mechanical deformation If an alternating voltage is applied, the crystal repeatedly expands and contracts. At sufficiently high frequency, these oscillations can produce ultrasound waves. An ultrasound transducer can therefore perform two jobs: Electrical pulses → crystal vibration → ultrasound.
Reception
Returning ultrasound → crystal vibration → electrical signal.
Formula / Key Relation
Inverse effect: Electrical → Mechanical Direct effect: Mechanical → Electrical
Remember
- Inverse effect: Electrical → Mechanical
- Direct effect: Mechanical → Electrical
