| Abstract |
This paper Presents the fabrication and test of a micropump that can be applied to an implantable cerebrospinal fluid shunt system for hydrocephalus patients The proposed micropump consists of a pair of corrugated parylene diaphragm chambers and a set of nozzle and diffuser. The electromagnetic force drives the diaphragms and pumps the fluid. The static or dynamic characteristics of the fabricated devices have been obtained experimentally. The site of the micropump is 14 × 12 × 8mm^3. The flow rate increase by about 3 mell/h was observed in the operational pressure range the micropump. |
