Bimorph information


Bimorph cantilevers used as micromechanical linear actuator:
1 - substrate
2 - piezoelectric layer
3 - passive layer
4 - mechanical contact area
5 - track

A bimorph is a cantilever used for actuation or sensing which consists of two active layers. It can also have a passive layer between the two active layers. In contrast, a piezoelectric unimorph has only one active (i.e. piezoelectric) layer and one passive (i.e. non-piezoelectric) layer.
