1. a device or structure composed of two layers of material (such as piezoelectric crystals or metals) bonded together, which bends or flexes when subjected to an electric field or temperature change
Usage: technical; used in engineering and materials science

Examples

• The bimorph actuator converted electrical signals into mechanical motion.
• Engineers designed a bimorph sensor to detect minute vibrations.
• The piezoelectric bimorph bent when voltage was applied across its layers.
• Bimorph strips are commonly used in microelectromechanical systems.
• The bimorph element responded quickly to temperature changes in the device.
