A 5 mm dia. x 12 mm (when closed) spring made from shape memory alloy (NiTi). At room temperature this spring is soft enough to pull out to approximately 50 mm by applying a small force. When heated to 70°C by passing an electric current through it, the spring contracts to its original length with useful pulling force (equivalent to lifting 0.5 kg weight).
