Abstract
Recently, in various fields, the necessity for small and highly sensitive micro fluidic analysis system has increased. In this report, we have considered creating a micro fluidic device with a blood extraction mechanics. A substrate with a 3mmx8mm reservoir of 5mm in depth was covered with a laminate heat-hardening resin film and adhered laminate at vacuum atmosphere. After that, we attached a 25G hypodermic needle on center of covered resin film. When we tap the hypodermic needle to the skin, resin film is broken by moving hypodermic needle. At the same time, blood is drawn into the reservoir. Using this device, we could draw ink into the reservoir. In this experiment, we used ink instead of human blood.
