A local network of implants uses your body as the wiring
摘要
佐治亚理工学院的研究团队开发了一种植入式设备网络系统，利用人体组织而非天线和无线电波传输信号，使起搏器、胰岛素泵等原本独立工作的植入设备能够相互协调。研究指出，蓝牙低功耗和近场通信等无线电协议不适合体内数据传输，主要问题在于功耗：蓝牙组件激活时可使植入设备电池寿命缩短多达90%。
Most implants like pacemakers and insulin pumps work in isolation. To help them coordinate with each other, a team of Georgia Tech researchers built a networking system that sends signals through body tissue instead of antennas and radio waves.
Radio problems
Implants that communicate today mostly rely on radio protocols like Bluetooth Low Energy or near-field communication (NFC). Both are a poor fit for in-body data transfer, says Alex Abramson, a Georgia Tech engineer and co-author of the new study.
The first problem is power. “If you want an implant to remain in an active state such that it can respond within milliseconds, it's very difficult to do that with the Bluetooth system,” Abramson said. According to the paper, Bluetooth components, when they’re activated, can cut an implant's battery life by up to 90 percent.
