Development of Micro Titanium Needle

The goal of the university research team was to invent a blood-sampling device using BioMEMS (biological microelectromechanical systems) technology featuring an extremely fine tube, and a design that mimics the blood aspiration mechanism of a female mosquito. This new needle technology makes it possible to collect less than 1 micro liter of blood when checking blood sugar levels thereby improving the comfort of the patient.

The features of this new production technology include its use of precious metals that have high melting points as the tube material, which is then deposited on a linear surface. Subsequently, only the surface material is removed to create a hollow structure. This technology reduces defects, improves rigidity, and can produce complex forms coated with pharmaceutical agents.
