Abstract
The invention relates to a piezoelectric actuation structure including at least one strain gauge and at least one actuator produced from a stack on the surface of a substrate of at least one layer of piezoelectric material arranged between a bottom electrode layer and a top electrode layer, at least a portion of the stack forming the actuator being arranged above a cavity produced in the substrate, characterized in that the strain gauge is a piezoresistive gauge located in the top electrode layer and/or the bottom electrode layer, the layer or layers including electrode discontinuities making it possible to produce said piezoresistive gauge. The invention also relates to a method for producing such a structure.
