Cover Story: Nature-inspired actuators are used to carry out effective motions based on the flexibility of natural creatures. This study presents an actuator that can simulate the motion of an elephant's trunk in several degrees of freedom. Actuators made of soft polymers that actively respond to external stimuli were integrated with shape memory alloys (SMAs) to mimic the flexible body and muscles of an elephant's trunk. The intended actuator is a soft gripper that combines a flexible polymer and SMAs to mimic an elephant trunk's flexible and effective gripping action. View this paper
