Abstract

A method of forming a piezoelectric or electrostrictive actuator comprises the step of laying on a substrate a finely divided piezoelectric or electrostrictive material (140) and a binder (141) as a matrix, the rigidity of which is substantially equal to that of the piezoelectric or electrostrictive material itself. The layer formed in this way can be extremely thin and therefore can have a greater piezoelectric effect.
