Singal-to-noise Ratio Enhancement Using 3-D Sensing Filaments in Structure-Induced Micro Fluid Turbulence

We analyze signal-to-noise ratio enhancement of sensing filament array considering micro turbulence induced when fluid flows through its three-dimensional structure. Combined with surface area, a factor of 10⁵~10⁶ can be expected compared to 2-D sensing array, making it possible to sense ultra-low concentration contents in fluid flow.
