Mechanochemical actuator


An actuator that converts chemical energy directly into mechanical work.

Since a mechanochemical actuator uses chemical energy for the power source, its efficiency is independent of its size. Contracting and expanding force is obtained by changes of internal energy at different levels, from the molecule to polymer conformation, interaction between polymers, to polymer bridge, against the stimuli from the outside. Examples of application developed so far are robot hands, and artificial legs. Application to clamps that carry out mechanical operations at the molecular level is also expected.
