Sustainable Flexible Electronics Based on Fish Gelatin

Abstract

Flexible electronics are of critical importance for medical devices, portable electronics, smart textiles, energy storage, communication and sensor systems [1,2]. However, the lifetime of electronics is becoming shorter, which poses a growing ecological problem. Therefore, it is urgent and necessary to find sustainable and cost-efficient materials to replace the crude oil-derived polymers that are commonly used in flexible electronics. To this end, fish gelatin (FG) extracted from fish scales could provide an eco-friendly and biodegradable alternative to plastic for use in flexible electronics. Fish scales are inedible and malodorous kitchen waste, and >2 million metric tons of fish scales are discarded each year. This talk will introduce our recent works on FG-based flexible electronics, including flexible electroluminescent devices and triboelectric nanogenerators (TENGs) [3-6]. The properties of FG films, the structure design and the performance of flexible electronic devices will be briefly discussed. These works may pave a new way to green and sustainable flexible electronics.
