Abstract
Shape memory alloy actuators comprising at least one hollow helical spring with an array of parallel shape memory alloy wires enclosed within or parallel and attached to each of the at least one hollow helical springs. Insulative end caps are attached to end of the at least one hollow helical springs, the insulative end caps defining electrodes for conducting electricity to the arrays of parallel shape memory alloy wires. Voltage means are connected to the electrodes for selectively providing electrical energy to the parallel array of shape memory alloy wires, causing the parallel array of shape memory alloy wires to expand and contract, providing either motion or measurement functions. In one embodiment, at least three helical springs with an array of parallel shape memory alloy wires either enclosed within or situated in physical and electrical contact with each of the at least three helical springs are enclosed within the insulative end caps and are individually actuated to provide three-dimensional movement to the insulative end caps.
