Bimorphs
Bimorphs are a type of composite material or structure consisting of two separate layers or components that are bonded together, each with different physical properties or characteristics. When subjected to external stimuli such as temperature changes, electrical voltages, or mechanical stress, bimorphs can bend, twist, or deform in a controlled manner due to the differential expansion or contraction of the two layers. This unique property makes bimorphs useful in various applications including actuators, sensors, switches, and other devices where precise and reversible movements or responses are required.
