A Self-Commutated Helical Polypyrrole Actuator Fabricated by Filament Patterning

Reversible retaining attachment is a universal task in which bioinspired soft robotic solutions in the form of a helix may come in handy. In this letter, we propose an mm-scale non-metallic electroactive polymer (polypyrrole) helical actuator with a 3D multimode (elongation, rotation) actuation with
