Summary: Recent advances in flexible electronics have made significant progress in the development of wearable devices, such as electronic skin (E-skin). However, the issue of power supply remains a challenge for E-skin in terms of size, weight, and cost limitations. In this study, a thin, soft, stretchable self-powered tactile sensor based on the triboelectric effect is developed by combining trampoline-inspired mechanics design and processing techniques in epidermal electronics. With the assistance of microstructure modification using sandpapers, the TENG sensor shows improved electrical performance and high sensitivity for a broad range of pressure, making it suitable for integration with a glove for human-machine interfaces and pressure mapping applications. Overall, the developed sensor offers great potential for the next generation of self-powered E-skin.

Summary: This study presents a self-healing triboelectric nanogenerator (TENG) fabricated using self-healing polyimide (PI) for energy harvesting and motion sensing. The PI-based TENGs exhibited excellent intrinsic self-healing properties, attributed to dynamic disulfide bond exchange and flexible PDMS fragments in the PI backbone. The output performance of the TENG was significantly improved due to CF3 electron-absorbing groups and siloxane fragments in the PI backbone. Practical applications of self-healing PI-based TENGs, including energy harvesting for commercial electronic devices and joint motion sensing, were demonstrated.

Summary: Flexible pressure sensors are becoming increasingly important in various applications such as human health monitoring, soft robotics, and human-machine interfaces. A conventional approach to achieving high sensitivity is by introducing microstructures to engineer the sensor's internal geometry. However, this strategy results in a thicker sensor which impairs conformability on surfaces with microscale roughness. In this manuscript, a nanoengineering strategy is introduced to resolve the conflicts between sensitivity and conformability, resulting in the thinnest resistive pressure sensor with superior sensitivity and conformability.
