bimorph

(ˈbaɪmɔːf) or

bimorph cell

n
(Electronics) electronics an assembly of two piezoelectric crystals cemented together so that an applied voltage causes one to expand and the other to contract, converting electrical signals into mechanical energy. Conversely, bending can generate a voltage: used in loudspeakers, gramophone pick-ups, etc

A bimorph is an assembly of two materials -- in this case, graphene and glass -- that bends when driven by a stimulus like heat, a chemical reaction or an applied voltage.
A bimorph is obtained when two materials react to external stimulus; the team was inspired by origami to combine graphene and glass to create a bimorph that bends with any stimulus like heat, chemical reactions, voltage or just a prod.
