报告摘要：
Smart materials are widely used in sensors, actuators and robotics, and their multi-functional capabilities enrich engineering applications. As an example of smart materials, soft smart composite (SSC) which is based on shape memory alloy (SMA) and anisotropic polymer fibers embedded in soft elastomer matrix is introduced. Actuation characteristics of the SSC and its applications to various mechanical systems are presented. Another type of actuator, shape-memory knit actuator is developed in order to have low stiffness and stretchable features. Scaling down to meso/micro level, 25~40 micro meter thick SMA wires in SSC show 35 Hz, and light-driven actuation of thin SMA structure enhances the actuation frequency up to 1,600 Hz. Several SMA-based actuators and biomimetic robots are discussed in detail.
