Tohoku Univ. Technology ：3D Microcoil Fiber Fabrication Technology：T24-092
Applications: Medical Diagnostics, Microfluidics, Chemical Mixing, Cell Manipulation, etc.
Conventional microfluidic devices are typically fabricated on flat substrates using lithography—a standard semiconductor manufacturing technique. However, this approach is limited by its inability to create three-dimensional or non-planar channel structures, which restricts the functional complexity of the devices. To overcome these limitations, the research team developed a Rotary Thermal Drawing System. This breakthrough equipment enables the production of 3D helical channels and microcoil fibers. Beyond simple fluidics, this technology allows for the integration of electrical components, leading to novel applications such as advanced electrophoresis. Key features of this technology: ・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.
