In this paper, a linear actuator with a shape memory alloy (SMA) clamping mechanism for dual-slider positioning is proposed by using a single piezoelectric element (PZT). The linear actuator consists of an SMA clamping mechanism, a PZT, a permanent magnet, a steel plate, and a base with a guide way. The SMA clamping mechanism and the steel plate serve as a slider 1 and a slider 2, respectively. When the SMA clamping mechanism releases from the guide way, the slider 1 can be driven as an impact drive mechanism. On the other hand, when the SMA clamping mechanism clamps on the guide way, the slider 2 can be driven as a smooth impact drive mechanism. In the resting state, the SMA clamping mechanism clamps on the guide way to ensure the stability of the whole system. To investigate the performance of the SMA clamping mechanism and the linear actuator, a prototype was constructed with a compact size of 40 mm (L) × 15 mm (W) × 12 mm (H). Experimental results confirmed that the dual slides could be driven independently by clamping and releasing the SMA clamping mechanism. It was verified that both the sliders can achieve long motion ranges of several millimeters and high resolution of tens of nanometers.
