Abstract:
This paper presents a multi-layered piezoelectric nanosensor designed for robotic exoskeletons, aimed at enhancing neuro-muscular rehabilitation. Green-driven methods were used to achieve biocompatibility throught the incorporation of carbon-based nano-inks, reduced graphene oxide, and an optimized piezoelectric layer to enhance electrical conductivity under mechanical stress. These components are integrated with a triboelectric layer composed of a teflon-copper core. Electrical characterization tests demonstrate that the proposed sensor exhibits robust performance and high reliability, both critical issues for hand grasping sensing under rehabilitation scenarios.
