Zusammenfassung:[Display omitted] •Sandwich design of the soft actuator enables self-sensing capability.•Acting as electronic skin to measure the pressure and as actuator to provide haptic feedback.•High control resolution and uniform output forces are achieved by closed-loop control.•The proposed wearable glove provides an intuitive and efficient human–machine interface,•Applications demonstrate the promising potential for human-in-loop systems and metaverse. The intuitive and effective haptic feedback interaction is essential for human–machine interfaces. However, most current commercial haptic feedback solutions are rigid, simplex, and insufficient to fully immerse users in virtual and teleoperated environments. Here, we report the design, fabrication and performance of a low-cost and lightweight self-sensing actuator (SenAct) that provides accurate force and vibration feedback to recreate the tactile perception. The SenAct shows good performance such as fast response (10 ms), high robustness (>10,000 cycles), and large output force (up to 1.55 N) with high controllable resolution (up to 0.02 N) based on the real-time closed-loop control. It is capable of providing the corresponding haptic feedback to the wearer through external force or vibration signal input. With this prototype, we presented a haptic feedback glove that supports precise operation by enhancing immersion and comprehensive sensation. Furthermore, we demonstrated it could shape appropriate interaction in different scenarios, including touching or grasping objects in virtual reality and teleoperation, illustrating its potential applications in human-in-loop interaction system and metaverse.
