Synthetic Muscle electroactive polymer (EAP) based actuation and sensing for prosthetic and robotic applications

摘要: Ras Labs Synthetic MuscleTM – a class of electroactive polymers (EAPs) that contract and expand at low voltages mimic the unique gentle-yet-strong nature human tissue. These EAPs also attenuate force sense mechanical pressure, from gentle touch to high impact. This is potential asset prosthetics robotics, including manned space travel through protective gear assist robotics for unmanned exploration deep space. Fifth generation very robust attenuates impact non-Newtonian mechanisms. Various electrolyte solutions conductive additives were explored optimize these EAPs. In prosthetics, interface between residual limb hard socket prosthetic device pain point. EAP pads gently within using 1.5 V batteries will allow extremely comfortable, adjustable, perfect fit throughout day amputees. For robot grippers, linkages can be actuated sensors placed fingertips grippers tactile feedback. Onset actuation nano-level was determined 48 milliseconds, with macro-scale visible naked eye seconds. Smart based materials actuators promise transform prostheses robots, allowing treatment, reduction, prevention debilitating injury fatalities, further our by land, sea, air,
