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

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
