A novel soft electromagnetic actuator (SEMA) designed for enhanced force-to-weight ratios and excellent actuation transparency, making it ideal for wearable haptic devices. This innovative SEMA integrates soft Halbach magnet arrays with multi-phase coils for effective Lorentz force generation, and uses ferrofluid in the air gap for improved bearing functionality and heat conduction.
Key experiments have tested the feasibility of the design and the effectiveness of the insulation methods, with a shift towards using durable thermoplastic polyurethane (TPU) films due to their superior flexibility and moisture resistance. Advanced design with ferrofluid bearings, optimizing through continuous modeling and testing.
This project pushes the boundaries of soft actuator technology and wearable devices, providing insights into the future of user interaction and device design.
