Abstract

A driving system using an intercalation substance as a novel mechanochemical system includes an actuator using the intercalation substance and driven by exchange of solutions or by changing concentration of a solution, and a solution supplier that supplies the actuator with the driving solution or solutions. The actuator is composed of one or more cylindrical or fiber-shaped elements each extending in the expanding and contracting direction of the intercalation substance, or one or more film-shaped or plate-shaped elements each having a major surface extending vertically of the expanding and contracting direction of the intercalation substance. The driving system is used as artificial muscle, for example.
