ABSTRACT:
Apparatus including layer of polarizable material located between first and second electrodes. Polarizable material has block copolymeric composition including elastomeric domain blocks and conductive domain blocks. Method that includes providing layer of polarizable material having block copolymeric composition including elastomeric domain blocks and conductive domain blocks, first and second electrodes being on opposite surfaces of the layer. Method also includes applying voltage differential between electrodes, causing dimension of layer to change.
