A local network of implants uses your body as the wiring
Summary
Ars Technica reports on a Georgia Tech project (SWANS) that enables a local network of implants to communicate through body tissue rather than radio waves. The system uses a wearable hub to generate pulses that are picked up by injectable implants, enabling targeted actuation with ultra-low power compared to Bluetooth/NFC. Tests in tissue, pork, and rats show significant reach and potential medical applications, though data throughput is limited and human-tischexperiments are future work.
