Abstract

This paper presents the development and validation of a novel stretchable dry hybrid electrode for electrotactile stimulation and EMG recording, designed for integration into prosthetic socket liners. Three electrode prototypes were compared: (1) dry stretchable electrode; (2) electrode with elevated pads via plastic layering beneath; (3) electrode with 3D-printed conductive plastic atop the pads. Six able-bodies subjects were recruited to assess the active stimulation range and subjective comfort and preference. Electrodes 1 and 3 showed comparable sensation and discomfort thresholds (1.1-4.1 mA), while electrode 2 exhibited a reduced dynamic range and higher pad failure rate. Four out of six participants preferred electrode 1. A prolonged 6hour test with electrode 1 confirmed stable stimulation thresholds over time in a single subject. The initial results indicate the feasibility of novel dry textile-integrated electrodes for providing feedback in closed-loop applications.
