Fish scales could make wearable electronics more sustainable

Flexible temporary electronic displays may one day make it possible to sport a glowing tattoo or check a reading, like that of a stopwatch, directly on the skin. In its current form, however, this technology generally depends on plastic. New research describes a way to make these displays, which would likely be discarded after a single use, more environmentally friendly using a plentiful and biodegradable resource: fish scales.
