Piezoelectric ceramic bimorph

Bimorph as shown by two single-wafer and a glass fiber or carbon fiber sandwich posed. 

Because of the inverse piezoelectric effect of the piezoelectric ceramic sheet, when the forward voltage is applied to the bimorph, since the two piezoelectric ceramics having an opposite direction of polarization, the electric field directions of the two side surfaces and polarization directions are the same, while the other side of the field direction and polarization in the opposite direction, that is a party to do the expansion vibration, then the other side is doing contraction bending vibration amplitude bimorph change a lot. Displacement. When a negative voltage is applied, the vibration of the upper and lower surfaces of the ceramic sheets are opposite to the previous. 

Size 

Standard sizes as shown above. 

Other specifications can be customized according to user needs. 

Applications 

With such a power, and a displacement of the small displacement of the piezoelectric bimorph generates an electrical signal characteristic can be applied in many fields 

1, textile machinery needle selection device, such as Jacquard comb, needle selection, etc. 

2, automotive piezoelectric fluid valve 

3, medical equipment, such as ultrasonic detectors, insulin pumps, etc. to enhance collagen 

4, small piezoelectric pump 

5, energy harvesting power plant 

6, the blind typewriter
