Piezoelectric Accelerometers and Electricity Generation from Piezos
Piezo Aerospace Materials & Components: APC manufactures piezoelectric components for sensing applications used in the aerospace market
APC International manufactures a full range of piezoelectric products used in the aerospace industry. We offer five piezo materials, ready-to-use assembled piezo components, and custom designed piezoelectric ceramics.
APC’s 850 piezo material, a “soft” piezo material, is suitable for a variety of sensing applications found in the aerospace industry. APC 850 offers a high coupling factor, high charge sensitivity, high permittivity, and high piezoelectric charge coefficients.
Common piezo components made with APC 850 used in the aerospace industry include:
– Accelerometers
– Flow meters
– Gyroscopes
– Pressure sensors
APC also offers shear mode piezoelectric ceramics. to the aerospace market. Shear mode piezoelectric ceramics can provide greater sensitivity and displacement than standard piezo ceramics.

Electricity Generated Through Piezo Sources
Piezoelectric ceramics generate electrical voltages based on the volume of a ceramic and the amount of stress exerted resulting in a conversion of mechanical energy into electrical energy. The amount of voltage increases inline with the amount of stress applied and can be measured with the piezoelectric voltage constant.
Many ignitors utilize the piezoelectric effect to generate a voltage that can be sparked across an electrode gap to then ignite a combustible gas. Piezo ceramics can be used in fuel lighters, gas stoves, welding equipment, and applications where a large voltage, but low current, is required.
The electrical energy generated by a piezoelectric ceramic can be stored and then used as a power source. This electricity generation storage can be used in piezoelectric batteries. Piezoelectric batteries do not exhibit electromagnetic interference and therefore are ideal for powering interference-sensitive electronic circuits.
