The coronavirus pandemic has highlighted the importance of developing intelligent robotics to prevent infectious disease spread. Human-machine interfaces (HMIs) give a chance interactions between users and robotics, which play significant role in teleoperating robotics. Conventional HMIs are based on bulky, rigid, expensive machines, mainly focus robots/machines control, but lack adequate feedbacks users, limit their applications conducting complicated tasks. Therefore, closed-loop with both accurate sensing feedback functions is extremely important. Here, we present HMI system skin-integrated electronics, whose electronics compliantly interface whole body for wireless motion capturing haptic via Bluetooth, Wireless Fidelity (Wi-Fi), Internet. integration visual VR together into robotic demonstrates great potentials noncontact collection bio samples, nursing patients many others.

Highly-integrated, miniaturized, stretchable electronic systems based on stacked multilayer network materials

Science Advances, Journal Year: 2022, Volume and Issue: 8(11)

Published: March 16, 2022

Elastic stretchability and function density represent two key figures of merits for stretchable inorganic electronics. Various design strategies have been reported to provide both high levels density, but the densities are mostly below 80%. While stacked device layout can overcome this limitation, soft elastomers used in previous studies could highly restrict deformation interconnects. Here, we introduce multilayer network materials as a general platform incorporate individual components interconnects, without posing any essential constraint their deformations. Quantitative analyses show substantial enhancement (e.g., by ~7.5 times) elastic serpentine interconnects compared that based on elastomers. The proposed strategy allows demonstration miniaturized electronic system (11 mm 10 mm), with moderate (~20%) an unprecedented areal coverage (~110%), which serve compass display, somatosensory mouse, physiological-signal monitor.
