This electronic skin can heal itself — and then make more skin

In a quest to make electronic devices more environmentally friendly, researchers have created an electronic skin that can be completely recycled. The e-skin can also heal itself if it’s torn apart.
The device, described today in the journal Science Advances, is basically a thin film equipped with sensors that can measure pressure, temperature, humidity, and air flow. The film is made ofthree commercially available compounds mixed together in a matrix and laced with silver nanoparticles: w
