Researchers have developed an extremely stretchable artificial skin that emits light and responds to pressure.

A recently-developed artificial skin has been likened to that of an octopus due to its ability to stretch, respond to pressure and give off light. 

The skin is a major upgrade in hyperelastic, light-emitting capacitor technology--which relies on electrodes resting inside a silicone matrix. 

According to a summary of the findings, "To allow displays of different colors, the matrix in the researchers' design contains zinc sulfide that is doped with various transition metals that emit different wavelengths as electricity passes through. For example, blue light can be created with the presence of copper, or yellow light with magnesium. Tests of the material's elasticity reveal that its surface area can e
