Abstract
The purpose of this research project is to develop a compact and wearable human blood extraction and drug delivery system applying to analyze a blood sugar level as a health monitoring system (HMS), which is called "Mobile Hospital", without a centrifugal separator and a large scale blood sampling system such as conventional glucose level monitors. The design concept is Bio-MEMS from the female mosquito's blood suction mechanism. We will apply the developed device to the wristwatch type HMS. It consists of (1) a painless microneedle, (2) an indentation unit using a shape memory alloy (SMA) actuator, (3) a micropump for human blood suction using a piezoelectric microactuator, (4) a bio-sensor to detect and evaluate the amount of Glucose in extracted blood using an enzyme such as Glucose oxidase, and (5) an micropump for insulin dosage. In this paper, we have especially reported design, production and performance of the above (3) to (5).
