Wireless System Pinpoints Location of Ingestible Implants

An “in-body GPS” system was developed that can pinpoint the location of ingestible implants inside the body using low-power wireless signals. These implants could be used as tiny tracking devices on shifting tumors to help monitor their slight movements. The system, called ReMix, can...
