Unimorph

A unimorph or monomorph is a cantilever that consists of one active layer and one inactive layer.

[1] In the case where active layer is piezoelectric, deformation in that layer may be induced by the application of an electric field.

This deformation induces a bending displacement in the cantilever.

The inactive layer may be fabricated from a non-piezoelectric material.
