PneuMod: A Modular Haptic Device with Localized Pressure and Thermal Feedback
summary
A wearable array of pneumatically-actuated silicone bubble modules with an integrated Peltier and thermistor is built plus a force sensor, Velcro mounts, Arduino control and a solenoid valve manifold for fast inflation/deflation. Modules attach to sleeves, armbands, headbands, ankles and chest; demos place two chest actuators and one on each wrist and forehead. Technical tests quantify pressure and temperature response, and a user study on a forearm sleeve shows participants reliably distinguish shapes, motion patterns and warm/cold cues.
