A new class of soft, electrically activated devices mimics the expansion and contraction of natural muscles. These devices, which can be constructed from a wide range of low-cost materials, are able to self-sense their movements and self-heal from electrical damage, representing a major advance in soft robotics. Such soft robots contain tremendous potential for future applications as they adapt to dynamic environments and are well-suited to closely interact with humans.
A central challenge in this field known as “soft robotics” is a lack of actuators or “artificial muscles” that can replicate the versatility and performance ...
