Biomaterials offer great potential for enhancing the performance of humidity sensors, which
play a critical role in controlling moisture levels across different applications. By utilizing
environmentally friendly, sustainable, and cost-effective biomaterials, we can improve the
manufacturing process of these sensors while reducing our environmental impact. In this
study, we present a high-performance humidity sensor that utilizes purple sweet potato peel
(PSPP) as both the substrate and sensing layer. The PSPP is chosen for its polar hydrophilic …
