Abstract
An apparatus including polymer configured to have a first state or a second state, wherein the volume of the polymer in the first state is different to a volume of the polymer in the second state; an actuator configured to be controlled by an input signal to cause the polymer to change between the first state and the second state; and a constraint configured to constrain the polymer in at least a first direction when the polymer changes between the first state and the second state.
