Abstract: A self-powered textile-integrated wearable apparatus in the form of a sock for continuous gait parameter extraction and predictive rehabilitation assessment. The apparatus comprises a piezoelectric nanogenerator (PENG) array (101) structurally embedded within the textile substrate at heel (101a) and forefoot (101b) plantar pressure regions, converting mechanical strain from foot-ground interaction into electrical energy. A power harvesting and regulation unit (105) simultaneously rectifies harvested energy for circuit operation and conditions the signal waveform for biomechanical analysis, providing dual functional utilisation of the piezoelectric output. An ultra-low-power processing unit (102) powered exclusively by harvested energy extracts gait parameters including stride length, cadence, gait asymmetry, and stance-to-swing ratio using hardware-optimised computational structures. An edge AI module (104) evaluates extracted parameters against locally stored predictive models to detect rehabilitation plateau, early functional deterioration, and fall risk. A wireless communication module (103) transmits only processed parameters and encrypted model weight updates via a federated learning protocol, ensuring no raw biometric data leaves the device. The apparatus operates without batteries, external power sources, or cloud-based processing, and is applicable in stroke rehabilitation, neuromuscular disorder monitoring, tele-rehabilitation, and sports recovery.
