Nanoporous copper as an inexpensive electrochemical actuator responsive to sub-volt voltages

Metallic actuator materials have been comprehensively studied during the last twenty years, but the studies have been limited to noble metals to date. Here we report reversible dimensional changes in nanoporous copper made by dealloying an Al-Cu alloy. A strain amplitude of 0.11% is obtained using s...
