Abstract: Biocomposites as bio-inspired materials are produced from renewable resources that are organic and ecofriendly alternative materials. To improve the lifestyle of human beings as well as enhancing the environmental indices, functional bio-materials are now implemented in various promising industries. This work has systematically discussed and highlighted the implementations and trends of functional bionic materials in high tech industries, which are necessary for developing modern societies. Various medical, electronic, food and pharmaceutical applications have been considered. Bio-inspired materials are used to develop more sustainable possibilities to increase environmental conservation while maintaining customer satisfaction. Biopolymers were found employed in several sectors for various functional bio-products including organic thin-film transistors, organic phototransistor, emitting diodes, photodiodes, photovoltaic solar cells, hybrid dental resins, sustainable pharmaceuticals, and food packaging. They are used to create sustainable bio-products for energy storage and harvesting, bone regeneration, nerve damage repair, drug applications and various other industrial subcategories.
