Cell driving type actuator and method for manufacturing the same |
摘要 |
A piezoelectric/electrostrictive actuator includes a plurality of piezoelectric/electrostrictive elements arranged in comb teeth-like alignment on a base plate. The actuator is driven by means of dislocation of the piezoelectric/electrostrictive elements. The cell driving type actuator is characterized in that each of the cells is formed independently from adjacent cells by positioning cover plates between two adjacent piezoelectric/electrostrictive elements. Thus, there is provided a piezoelectric/electrostrictive actuator wherein a heating process at a high temperature can be applied and mass production at low cost is possible. The actuator includes cells with slit portions having a width of 60 mum or less and a high aspect ratio and can be activated with high electric field strength, and great displacement can be obtained with small electric field strength.
