Research Progress in Electroactive Polymers for Soft Robotics and Artificial Muscle Applications

Polymers, Journal Year: 2025, Volume and Issue: 17(6), P. 746 - 746

Published: March 12, 2025

Soft robots, constructed from deformable materials, offer significant advantages over rigid robots by mimicking biological tissues and providing enhanced adaptability, safety, functionality across various applications. Central to these are electroactive polymer (EAP) actuators, which allow large deformations in response external stimuli. This review examines EAP including dielectric elastomers, liquid crystal elastomers (LCEs), ionic polymers, focusing on their potential as artificial muscles. EAPs, particularly electronic varieties, noted for high actuation strain, flexibility, lightweight nature, energy efficiency, making them ideal applications mechatronics, robotics, biomedical engineering. also highlights piezoelectric polymers like polyvinylidene fluoride (PVDF), known biocompatibility, ease of fabrication, contributing tactile pressure sensing robotic systems. Additionally, conducting with fast speeds strain capabilities, explored, alongside magnetic composites (MPCs) biomedicine electronics. The integration machine learning (ML) the Internet Things (IoT) is transforming soft enhancing actuation, control, design. Finally, paper discusses future directions self-healing composites, bio-inspired designs, sustainability, continued IoT ML intelligent, adaptive, responsive
