A team of Georgia Tech researchers has developed a networking system that allows medical implants to communicate by sending signals through body tissue. This approach replaces the antennas and radio waves currently used for data transfer between devices.
Most existing implants, such as pacemakers and insulin pumps, operate in isolation. To enable coordination, the new system bypasses traditional wireless protocols. Alex Abramson, a Georgia Tech engineer and co-author of the study, noted that standard radio methods are poorly suited for in-body applications.
Current implants primarily rely on Bluetooth Low Energy or near-field communication (NFC). Abramson identified power consumption as a primary obstacle with these technologies. He explained that maintaining an implant in an active state capable of responding within milliseconds is difficult using Bluetooth systems. The research paper states that activating Bluetooth components can reduce an implant's battery life by up to 90 percent.
