Abstract

Fabrication method of straight micro-coils of stainless steel was investigated for applying the coils to bio-measurements. As a non-magnetizable material, SUS304 stainless steel pipes with outer and inner diameters of 100 and 60 μm were used. Specimen pipes coated with positive resist films were exposed to a violet laser beam, and helical resist patterns were delineated. The pipes masked by the helical patterns were wetly etched in electrolytic etchant composed of sodium chloride, ammonium chloride, and boric acid. As a result, micro-coils with almost homogeneous widths were successfully fabricated. The calculated spring constant was in a favourable range of 0.7-2.4 N/mm. The new micro-coil fabrication method is feasible for the use of bio-device components.
