Demonstrating NeuroFlux: A Non-Invasive Peripheral Magnetic Stimulation Device for Multimodal Haptic Feedback

Abstract

We demonstrate NeuroFlux, a wearable armband that delivers multimodal haptic feedback through non-invasive peripheral magnetic stimulation. Unlike conventional haptic devices limited to either tactile or kinesthetic modalities, NeuroFlux stimulates peripheral nerves to independently evoke both muscle movements and localized skin sensations. Our system features a custom-designed control circuit and a multi-coil armband, enabling precise, real-time control of stimulation location and intensity. This hardware innovation significantly expands the design space of haptic feedback by bridging kinesthetic and tactile modalities through a single, compact device. In our demonstration, participants will experience a wide range of magnetically induced haptic sensations, including independent stimulation of muscular and cutaneous nerves in the forearm. The setup includes interactive tasks that showcase NeuroFlux’s ability to generate diverse haptic effects such as finger flexion, wrist movement, as well as immersive virtual reality object interactions. By offering hands-on exposure to peripheral magnetic stimulation, we aim to spark new research directions in multimodal haptic feedback and make neural stimulation more accessible to the HCI community.
