For highly conformable and universal transport devices, bioinspired dry adhesion systems with reversible molecular attractions (e.g., van der Waals forces, capillarity, or suction stress) between the engaged surfaces have recently become favorable for various dry/wet processes in flexible devices medical applications. In addition, many efforts been made switchable attachments of such adhesives by employing costly sophisticated as mechanically deformable chucks, UV-radiating components, fluidic channels. this work, we propose a simple electrothermally actuating device based on an octopus-inspired microsphere-embedded sucker (OMS). The adhesive suckers offers enhanced surfaces, accordance investigation geometric materials parameters novel architecture maximizing interactions. Inspired muscle actuation octopus tentacles, laminate reactive poly(3,4-ethylenedioxy thiophene):poly(styrenesulfonic acid) (PEDOT:PSS) layer backside OMS patch. By controlling inputs electrical energy, our assembled actuator may actively expand contract reversibly to induce detachments. Our can be integrated onto robotic arm attach release against thin objects.
