Wearable Focused Ultrasound Stimulation for Peripheral Nerve Pain Management

This study will evaluate the feasibility of a novel wearable focused ultrasound (FUS) device for peripheral nerve stimulation in healthy volunteers. The aim is to assess device operability, usability, tolerability, and physiological responses during standardized sensory tests. Each participant will complete nine \~1-hour study sessions across multiple days, including cold pressor and algometry tasks performed under baseline, sham, and active FUS conditions.
