The first multifunctional elastic (650) fiber that can scavenge biomechanical energyelectromagnetic energy from surrounding electrical appliances is developed as a wearable power providervarious self-powered sensors. These findings optimally unify mechanical freedomthe capability of harvesting biomechanical energyelectromagnetic energy from surrounding electrical appliances as well as self-powered sensing in a single fiber.

Our team has developed a layer-by-layer hydrophilic membrane (LHM) as the “bendable water-enabled portable power banks”. It is bendable, cost-effective, lightweight, environmental-friendly,high-efficient. Moreover, it could achieve high-voltage (~0.8 V), high-current (~80 μA)long-lasting (4 hr) power output by dropping a few drops of DI water (or electrolyte solutions), which can be described as a "black technology" towards green clean energy.

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

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.
