Abstract
Embodiments of a product such as a stimuli-responsive product can comprise a shape memory component and a nanofiber component that forms a fibrous microstructure or network. The resulting product can be responsive to stimuli, such as electrical stimuli, in a manner that cause the product to deform, deflect, and rebound. In one embodiment, the product can comprise an epoxy and a continuous non-woven nanofiber, the combination of which provides a product with enhanced actuation speed.
