A local network of implants uses your body as the wiring
Summary
Researchers at Georgia Tech developed a new system called SWANS that lets implants in the body communicate by sending signals through body tissue instead of using radio waves. This method uses electric pulses and small implants to share information quickly and with less power than current Bluetooth-based systems.Key Facts
- Most implants today use radio signals like Bluetooth to communicate, but these drain battery power quickly and don’t travel well through body tissue.
- SWANS sends signals through body tissue using electric pulses, inspired by how nerves communicate with ions in the body.
- The system includes a wearable hub, a patch with microneedles, and many tiny injectable implants that can sense or act on signals.
- The implants respond only to specific signal strengths and durations, so they can distinguish themselves among many signals.
- The wearable hub controls the implants and has enough power to keep the small implants simple and energy-efficient.
- Implants can be as small as those injected by syringe, avoiding the need for surgery.
- This technology could allow multiple implants to work together inside the body for better health monitoring or treatment.
- Each implant’s settings need to be adjusted for each person and placement in the body to work properly.
