How about small cheap 5v relays? They can be had for a few dimes each and can be cut into to reveal the moving parts. Even tiny ones have a surprising amount of force. One might be able to connect to the innards to make an array of binary actuators that could rest against skin. It would probably be hard to beat the power efficiency.
