Fluids can be well mixed by using a helical flow channel inside a microfiber
Conventional microfluidic devices are typically manufactured on flat substrates using lithography—a standard semiconductor fabrication technique. However, this traditional approach is largely limited to two-dimensional (planar) channel structures, making it difficult to create complex, three-dimensional fluid paths. To overcome these limitations, the inventors developed a Rotary Thermal Drawing System. This breakthrough device enables the production of hollow spiral microfibers with complex 3D structures. By leveraging this technology, the inventors have successfully designed a highly efficient Micromixer that uses internal helical channels to achieve uniform mixing of fluids, such as chemicals and reagents. Key Technical Advantages: ・Flexible design is possible: the fiber material (e.g. high‑strength material, elastic materials), diameter size, pitch, shape (liner or spiral), hollow or not, etc. ・Portable size of the equipment: Saving space and easy to handle.

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.
