ELASTIC BODY INSPECTION METHOD, INSPECTION DEVICE, AND DIMENSION PREDICTION PROGRAM

摘要

There is provided an inspection method for inspecting a piezoelectric/electrostrictive actuator including a piezoelectric/electrostrictive body and at least two electrodes. The inspection method picks up frequency characteristic when the piezoelectric/electrostrictive actuator is vibrated and according to the frequency characteristic, the displacement amount of the piezoelectric/electrostrictive actuator is measured. Thus, the method can inspect the piezoelectric/electrostrictive actuator with a high accuracy without disassembling or destroying the actuator and without performing actual drive as a product.
