GoKawiilGeorgia Tech researchers build implant network that uses body tissue instead of radio signals
Georgia Tech engineers led by Alex Abramson developed a system called SWANS that lets implanted devices communicate by sending electrical signals through body tissue rather than Bluetooth or NFC radio waves. The system mimics ionic conduction used by neurons, passing voltage signals through tissue instead of nerves to coordinate multiple implants like pacemakers and insulin pumps.
GoKawiil's interpretation of the reporting above, not reported fact.
Current implant communication methods drain battery life quickly and lose signal strength after just a centimeter of tissue, according to Abramson, limiting how implants can coordinate with each other. A tissue-based signaling approach could allow smaller, less power-hungry implants that might be injected rather than surgically placed, potentially expanding what kinds of connected medical devices become practical.
- SWANS transmits data through body tissue via ionic conduction rather than radio waves
- Bluetooth can cut implant battery life by up to 90 percent when active, per the study
- Radio-based implant communication degrades badly beyond about one centimeter of tissue
