Self-Healing Skin Developed For Robots

Hmm, where have we seen this before? Stanford University scientists have created a multi-layered, self-healing electronic skin for robots and prosthetics that has a sense of touch and can realign itself autonomously when cut. 

Layered Polymers 

The research team created the synthetic skin using thin layers of rubber, latex (natural polymers), and other polymers including PPG (polypropylene glycol) and PDMS (polydimethylsiloxane, also known as silicone). These layered polymers were chosen because they have rubber-like electrical and mechanical properties, biocompatibility, and can be mixed with nano or microparticles to enable electric conductivity and hydrogen bonding can be used to turn them into a durable, multilayer material that resembles human skin.
