Implant-to-implant wireless networking with metamaterial textiles
AbstractImplanted bioelectronic devices have demonstrated significant utility for health sensing and therapy, yet interconnecting distributed implants across the body remains a critical challenge. This work demonstrates direct implant-to-implant wireless networking at human-body scale using wearable metamaterial textiles. Validated in a porcine model, the system achieves closed-loop control of heart rate between an implanted loop recorder and a vagus nerve stimulator over distances exceeding 40 cm — fully compatible with standard BLE protocols. The approach opens pathways to post-surgery monitoring, long-term closed-loop drug delivery, and next-generation human-machine interfaces.
