The Design and Fabrication of Pressure Detection Head

Abstract

In this research, a tiny size non-invasive pressure detection head is designed and fabricated. It serves as an essential component of the multi-functional sphygmus detection system. When the pressure detection head places upon the correct position at wrist, it transmits the pulse pressure from the touch membrance through the silicon oil, and then to the pressure die. This kind of structure will provide a stable data acquisition for pulse pressure sensing. To verify the performances of the pressure detection head, a pressure test bench together with standard testing procedure is developed to gather information on the tested signals. The test results indicate that the designed pressure detection head is feasible and can be used for sphygmic diagnosis in medicine.
