Enabling High Temporal-Resolution Remote Monitoring in Resource-Constrained Implantable Medical Devices with Human Body Communication

Continuous remote monitoring of implantable medical devices, such as pacemakers, is limited by the high power consumption and security concerns of traditional wireless technologies like Bluetooth. In this work, we investigate Electro-Quasistatic Human Body Communication (EQS-HBC) as an alternative, leveraging the body itself as a communication channel between implants and werable devices. EQS-HBC achieves real-time, high-throughput data transmission at power levels approximately 100 times lower than Bluetooth, enabling millisecond-resolution monitoring with minimal impact on device longevity. Through system-level optimization of sensing, memory, and communication, we demonstrate that EQS-HBC can support high temporal-resolution, secure data exchange without the high battery life penalties of current Radio-Frequency (RF) based solutions. These results highlight EQS-HBC’s potential to transform remote care for patients by making truly continuous, personalized monitoring feasible.
