Image that your cell phone can be self-poweredable to self-healing after damagerobots in Sci-fi movie have self-poweredself-healable skins. Here, we present the first energy-harvesting triboelectric artificial skin that is entirely, intrinsically,autonomously self-healablesimultaneously highly transparentextraordinarily stretchableable to drive via self-generating

Nano-sized silicon reacts rapidly with most water solutions to form pure hydrogen. However, high costlow availability are major issue. Our group has developed novel nano-sized silicon mass-production process, greatly improves its feasibilitycost for hydrogen generation. The in-time hydrogen generation by nano-size silicon, fuel-cell systemlithium ion battery system are all well integrated into one portable power system, which can satisfy general personnel electricity demand for some special conditions, such as battle field, emergency caseremote regions.

The self-powered sensing system realizes self-powered wireless wearable pressure sensing modules, self-powered intelligent environment sensing robots,self-powered smart window, which can carry out self-powered sensing signals combined with the transmission of the Internet of Things. Functions such as medical monitoring aidsautomated environmental quality sensing. In the future, this system opens a window towards automatic monitoring of environmental analysispersonal smart healthcare.
