Which of the following is NOT a Piezoelectric transducer material?
Which of the following is NOT a Piezoelectric transducer material? Correct Answer Calcium farnate
A piezoelectric transducer is an electrical transducer which is used to transform the mechanical energy used in the material's deformation into electrical energy and vice-versa.
They have the property of producing electricity on applying a force or pressure over them under specific arrangement.
Also they can work in inverse by transforming the electrical signal applied across them into vibrations.
Piezoelectricity means "electricity by pressure".
- An electric transducer which uses properties of piezoelectric materials for conversion of physical quantities into electrical signals is known as piezoelectric transducer.
- Piezoelectric materials exhibits the property of piezoelectricity which means application of any kind of mechanical stress or strain leads to the generation of an electric voltage that is proportional to the applied stress.
Naturally Available materials: Quartz, Rochelle salt etc.
Artificially manufactures materials: Barium titanate, Lead zirconate titanate, Lead titanate et
Conclusion: option 4 is correct. calcium formate is not a piezoelectric transducer material.
Additional Information Applications of piezoelectric materials:
- As piezoelectric materials cannot measure static values these are primarily used for measuring surface roughness, in accelerometers and as a vibration pickup.
- They are used in seismographs to measure vibrations in rockets.
- In strain gauges to measure force, stress, vibrations etc.
- Used by automotive industries to measure detonations in engines.
- These are used in ultrasonic imaging in medical applications.
