Ingestible device

Battery-Free device that can be fixed at a specific location
Enabling sensing of the digestive system and integrated treatment

Overview

　The development of ingestible devices for testing and treatment in the body is underway.Because ingestible devices are small and have a limited power supply capacity, they have limitations in long-time operation and functional loading. In addition, because conventional devices are moved by the movement of the digestive system such as the small intestine, it is difficult to perform functions such as measurement and medication at a certain location for a long time.
　The ingestible device of the present invention is a ring-shaped device with coil wiring that is embedded in a small, folded state when ingested, and expands at a specific location to be fixed within the organ. Since the coil diameter is increased by expansion, efficient wireless power supply is possible by dielectric coupling with a coil outside the body. In addition, since the device is fixed at a specific location in the digestive organ when the coil is expanded, it is possible to measure time changes and administer medication at an appropriate location and time.
