MagTex: Machine-Knitted Magnetoactive Textiles for Bidirectional Human-Machine Interface
summary
MagTex combines soft magnetized silicone fibers and copper wire coils knitted on a digital machine to make a single-layer wearable that both senses motion and produces haptics. It uses the galvanomagnetic effect for localized vibration and electromagnetic induction for sensing, with a three-layer stackable PCB (power, amplifier+MCU, haptic driver). Tests show single-layer interlock knit gives the strongest field, a 5-person study finds low frequency plus high current most perceivable, and washing preserves sensing signals.
