Abstract

Printed electronics and paper electronics are relevant topics that promise a tremendous increase and their incorporation in gadgets for daily applications with a very short lifespan. This will fulfill special niches such as the Internet of Things and smart packaging, for instance. However, the printed electronics applications must not contribute further to the huge amount of e-waste generated nowadays, and for this reason, it is imperative to develop fully biodegradable and non-toxic printed electronics. In line with this global trend, researchers from the "Faculdade de Ciências e Tecnologia, UNESP, Presidente Prudente" have been studying the depositions of conductive tracks using laser-induced graphene (LIG) or carbon-based ink, and electrolyte-gated transistors (EGTs) on a flexible substrate, like paper. Besides, the electrodes of LIG and the EGTs devices, associated with surface-enhanced Raman scattering (SERS) techniques, have been applied to develop sensors for monitoring water quality and detecting pesticides. This SPRINT application proposes to develop electronic devices based on sustainable nanomaterials aiming to obtain fully printed and all-biodegradable devices. The proposed study will be performed in collaboration with researchers from the "Centro de Investigação de Materiais" - CENIMAT (Portugal) and the University of Glasgow (Scotland). CENIMAT is recognized worldwide as a pioneer and at the forefront of paper-based electronic centers. This application also aims to create a suitable environment to formalize a more effective collaboration program between these teams in the near future. (AU)
