Abstract

Two kinds of switching micro fluidic chips called "Dead volume-free" micro fluidic chip for portable micro chemical devices have been developed successfully. The 10-directional switching valve chip and the sampling chip as components of the air pressure drive micro dispenser system were developed successfully. The first one is the sampling chip that divides liquid every 1μL or 0.5μL without any dead volume of sample by decompressing and compressing the air. This simple operation is caused by our original novel detection method of micro fluid and check valves of hat shape. The second is the switching valve chip that can select the outlet. This chip has a special rotary mechanism consisting of silicone rubber ring for leak-preventions and the precise auto-positioning mechanism. This chip can switch ten outlets by built-in micro solenoid (1N, 6V DC) under high leakage pressure (higher than 500kPa). Since the both of chips were fabricated using our original "hybrid microstereolithography" (hybrid-IH process), micro assembling and bonding are not needed.
