The growing demand for sustainable materials in the electronics sector has sparked interest in bioderived cellulose-based alternatives to traditional plastics. This study introduces a novel circular-gel that exhibits impressive properties, including mechanical toughness, ionic conductivity, self-healing capabilities, transparency, biodegradability, recyclability, and complete reliance on renewable components. Fabricated through a one-pot synthesis using entirely green processes, the circular-gel demonstrates exceptional toughness and good ionic conductivity. With nearly 100% transparency and stabilized by robust reversible physical bonds, this gel outperforms traditional fabrication methods. We showcase its potential across various applications, such as capacitive pressure sensors, resistive strain sensors, and transparent electrodes for dielectric elastomer actuators. Additionally, we present an innovative approach to producing insulating cellulose sheets from waste materials, employing eco-friendly purification techniques. These cellulose sheets are non-cytotoxic and well-suited for sensor fabrication. Notably, all cellulose materials are designed to biodegrade in natural soil, contributing to a more sustainable lifecycle for electronic materials.
