In some embodiments, an actuator is provided having a graphite comprising
actuation region located between electrodes. An ion storage region is
located between the electrodes, with a separator region between the
actuation and the storage region. The actuation region may include
graphite structures embedded in an elastic matrix, the elastic matrix is
adapted to allow transport of chemical species capable of intercalating
within the graphite structures. A separator region is located between the
electrodes, along with an ion generation region capable of reversible
electrochemical production and elimination of ions. In some embodiments,
an actuator is provided with at least one of the electrode and the
counter electrode including graphite. An electrolyte therebetween having
a graphite intercalate ion source.
