We use air pump first to estimate the ability about improving the blood circulation. The system include pressure sensor with translation circuit to measure the blood pressure. Then we calculate the PWV from the popliteal artery blood wave and dorsalis pedis artery the toes. Before pumping leg the PWV more than the after pumping. Therefore, under the right time and the right pressure, the flow in the blood vessel can be driven forward to overcome the resistance encountered downstream. Since the blood pressure and the flow rate is monitored for the feedback control system, the function of the mechanical pump can be verified and optimized with reasonable safety for long term application. In this study, the optimum control parameters for the mechanical stimulation will be identified in the clinical application for diabetes mellitus.application/pdf295444 bytesapplication/pdfzh-TW國立臺灣大學電機工程學系暨研究所心跳周期機械式壓縮脈波波 速[SDGs]SDG3reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/7901/1/902314B002356.pdf
