Soft, Sustainable, and Sensitive: Biopolymer-Based Hydrogels as Recyclable Temperature Sensors for Skin-Integrated Electronics.

ABSTRACT: The development of sustainable, soft, and recyclable materials for skin-integrated electronics is critical for advancing wearable health monitoring while minimizing electronic waste. Here, chitosan-agarose-based hydrogels integrated with poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) are fabricated as recyclable, biocompatible, and thermoresponsive materials for flexible temperature sensors. The hydrogels are synthesized using a green and easy process, forming interpenetrated dual networks that exhibit high water content, mechanical compliance, and enhanced electroconductivity. Morphological analysis reveals highly porous interconnected structures, while Fourier transform infrared spectroscopy confirms the successful incorporation of PEDOT:PSS. The hydrogels display high
