Arthur T Knackerbracket has found the following story:

Skin-mounted electronic displays previously required long-lasting plastic. Researchers have created a bio-degradable film made from fish scales:

[Within] flexible temporary electronic displays [...] electricity-conducting and light-emitting components are layered onto a transparent film. To make them flexible enough to withstand the bending required to stay on skin or other soft surfaces, researchers have so far relied on films made of plastic -- a substance derived from fossil fuels, a limited resource and a source of pollution. Hai-Dong Yu, Juqing Liu, Wei Huang and colleagues wanted to find a more sustainable and environmentally friendly material for the film. They settled on gelatin derived from collagen in fish scales, which are usually thrown away.
