Both shape memory and self-healing polymers have received significant attention from the materials science community. The former, for their application as actuators, self-deployable structures, medical devices; latter, extending lifetime of polymeric products. effects can be stimulated by heat, which makes resistive heating a practical approach to trigger these effects. Here we show conductive ...

Sequential glass and melting transitions in semi-crystalline shape memory polymers (SMPs) provide great opportunities to design generate multiple shape-memory effects (SMEs) for practical applications. However, the complexly dynamic confinements of coexisting amorphous crystalline phases within SMPs are yet fully understood. In this study, an interfacial confinement model is formulated describe...

Minimally invasive implantation of subdural electrodes can dramatically benefit the patients with various neurological diseases. In modern clinical practice, procedure electrode arrays remains traumatic for and increases postoperative infection risk. Here we report a design insertion technique thermally activated shape-memory polymer-based array that recover up to ten times length deformation. ...
