Implant-to-implant wireless networking with metamaterial textiles

Abstract

Implanted 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.

Wireless battery-free body sensor networks using near-field-enabled clothing

Abstract

Networks of body-worn sensors enable continuous physiological measurement for clinical diagnostics, athletics, and human-machine interfaces. Existing near-field approaches require close proximity between each sensor and a readout device, severely limiting body-scale coverage. This work demonstrates near-field-enabled clothing that establishes wireless power and data connectivity between multiple distant points on the body, creating a network of battery-free sensors interconnected simply by proximity to a functional garment — enabling seamless, body-scale health monitoring without any batteries or wires.

§02 — About

From flexible PCBs to the human body.

I'm a Senior Research Engineer at Dyson, working on new product categories at the intersection of hardware, wireless systems, and human physiology. Before Dyson, I spent several years at the National University of Singapore building wireless, battery-free bioelectronics — from near-field-enabled garments for body sensor networks to implant-to-implant communication systems woven into metamaterial textiles.

My work has appeared in Nature Communications, Nature Electronics, and Science Advances. I care about systems that are robust, manufacturable, and quietly invisible once they're on — or in — you.
