Abstract
A portable device includes a case having wall portions, a battery arranged within the case, and a polymer membrane arranged between at least one of the wall portions and the battery. The polymer membrane couples the battery to the at least one of the wall portions. The polymer membrane has a property of elastically changing at least one of the thickness and the length in a planar direction by being deformed in response to voltage application and restoring its original shape in response to the stoppage of the voltage application. The battery is caused to reciprocate by applying a voltage that changes periodically to the polymer membrane.
