Ultrastretchable adaptive epidermal bracelet based on integrated crosstalk-free dual-mode sensors for accurate human-machine interactions

The sensor array is further monolithically integrated onto a continuous organohydrogel film with impressive self-adhesive and mechanical properties to construct an 8-channel integrated HMI bracelet using an electrochemical soldering strategy. The adaptive bracelet biointerface achieves a stretchability at least three times greater than the state-of-the-art (up to 100% strain), enabling it to conform to different individuals and body parts, and resulting in high movement recognition accuracy (97%).

Furthermore, the wireless smart bracelet is further leveraged for the remote and accurate control of various execution terminals (active rehabilitation robots, robotic arms/hands, etc.), highlighting its potential for various advanced HMIs.
