Innovative Self-Powered Sensing: Potential of Fabrigami and Electrospun Nanofiber-Based Triboelectric Nanogenerator for Joint Biomechanics Monitoring.

ABSTRACT: This work presents a high-performance, self-powered triboelectric nanogenerator (TENG) embedded into an origami-inspired fabric ("fabrigami") structure for real-time joint biomechanics monitoring. The device consists of electrospun polyvinylidene fluoride (PVDF) as the electronegative layer and silver-doped cellulose acetate (Ag-CA) as the electropositive layer, with enhanced surface charge density and mechanical durability. The fabrigami architecture amplifies contactseparation dynamics, enabling efficient detection of movements during joint motion while preserving conformability and air permeability. The optimized TENG based on 1.5% Ag in CA against PVDF exhibits remarkable electrical output characteristics, including an open-circuit voltage of 155.9 V, short-circuit current density of 8
