Bimorph
From Wikipedia, the free encyclopedia
A bimorph is a cantilever that consists of two active layers. These layers produce a displacement via:
- thermal activation (a temperature change causes one layer to expand more than the other).
- electrical activation as in a piezoelectric bimorph (electric field(s) cause one layer to extend and the other layer to contract).
A piezoelectric unimorph has one active (i.e. piezoelectric) layer and one inactive (i.e. non-piezoelectric) layer.
