Bimorph
A bimorph is a type of material or structure consisting of two layers that have different physical properties and are bonded together, causing the structure to bend or deform when exposed to an external stimulus such as heat, electricity, or light. This bending or deformation is a result of the differential expansion or contraction of the two layers in response to the stimulus, leading to a variety of applications in fields such as actuators, sensors, and energy harvesting devices.
