Flexible Displays from Biodegradable Fish Scales

Mar-18-20 Fish scales are typically discarded as waste, but researchers have found they could be an eco-friendly alternative to plastic used in flexible displays for electronic devices.

Gelatin was extracted from the scales and used to create an extremely thin film. Tiny nanowires were then introduced along with a light-emitting material. This resulted in a flexible electronic display that would biodegrade after only 24 days in soil; a lot quicker than the centuries it takes plastic to break down.

Further advantages include their high degree of transparency, low surface roughness, and low cost, which are useful in creating disposable wearable electronic devices.
