Abstract

This paper describes the development of the pneumatic micro dispenser system for ubiquitous microchemical devices, such as health care devices. The pressurization and decompression switchable micropump chip, the dispenser chip, and the 10-directional switching valve chip are developed successfully as components of this system. This system assembled with these chips can divide liquids into approximately 0.5 µl samples if its disk is simply rotated manually, and the system can be reused by simply replacing the dispenser chip where the sample exits.
