MagTics: Flexible and Thin Form Factor Magnetic Actuators for Dynamic and Wearable Haptic Feedback
summary
MagTics is a thin, flexible haptic skin that embeds hard magnetic actuator cells in a soft 3D‑printed case and runs from flexible PCBs, achieving latchable tactile pixels with low steady power. Each cell uses bistable electromagnetic latching to move a 2 mm pin and hold it without power, delivering 160–200 mN holding force; the prototype implements 4 actuated pins at 1.7 cm pitch, switches with 10–20 ms pulses, and yields usable wrist, arm, and finger feedback.
