Highly Conductive MXene/PEDOT:PSS‐Integrated Poly( N ‐Isopropylacrylamide) Hydrogels for Bioinspired Somatosensory Soft Actuators

Abstract Sophisticated sensing and actuation capabilities of many living organisms in nature have inspired scientists to develop biomimetic somatosensory soft robots. Herein, the design and fabrication of homogeneous and highly conductive hydrogels for bioinspired somatosensory soft actuators are reported. The conductive hydrogels are synthesized by in situ copolymerization of conductive surface‐functionalized MXene/Poly(3,4‐ethylenedioxythiophene)/poly(styrenesulfonate) ink with thermoresponsive poly( N ‐isopropylacrylamide) hydrogels. The resulting hydrogels are found to exhibit high conductivity (11.76 S m −1 ), strain sensitivity (GF of 9.93), broad working strain range (≈560% strain), and high stability…
