Multifunctional Untethered Soft Machines Driven by 4D Printed Electrically Responsive Actuators
Untethered robots, compared with their tethered counterparts, may bring enhanced autonomy. It is highly desirable to engineer multifunctional, lightweight, rapid, and low-voltage driven untethered soft robots that have enhanced adaptability and safer interaction capabilities. Here we present an untethered soft robot by a smart integration of 4D printed liquid crystalline elastomer (LCE) actuators with the associated electronics. The LCE artificial muscle, which consists of a modified LCE sandwiched between a polyimide based heating film and a silicone adhesive, not only has adjustable transition temperatures (39–46 °C) and modulus (0.61–2.57 MPa) but also has decent mechanical properties such as adequate rigidity…
