1. Researchers in China developed multilayer porous PVC gel artificial muscles using carbon nanotube-doped 3D-printed silicone electrodes, showing potential in human-machine interaction, medical rehabilitation, and flexible electronics. 2. The study optimized the ink formulation for both the CNT-PDMS composite and PVC gel to achieve desired properties for 3D printing. 3. Performance testing demonstrated the actuator's high deformability and responsiveness, indicating its potential for practical applications.
