3D Spiral Micromixer

Fluids can be well mixed by using a helical flow channel inside a microfiber

Overview

　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.
