A human skin is an ultimate substrate to introduce electronic functions with minimal invasiveness. Conformable thin film electronic devices can be integrated to skin for health-monitoring and/or machine interfaces. However, the feasibility of sensor patches or on-skin sensors for long term usage has not been proved due to gradual damage to the skins. Here we show that inflammation-free, breathable, ultrathin, lightweight, and stretchable sensors that can be directly attached on human skins for a long time have been successfully fabricated with a conductive nanofiber mesh structure. A one-week skin patch test has revealed that the risk of inflammation induced by on-skin sensors can be significantly suppressed by the nanofiber-mesh electronics with breathability, stretchability, and biocompatibility. A wireless system to detect touch, temperature, and pressure has been successfully demonstrated by nanofiber-mesh with extraordinary mechanical durability |
