A kind of electronic sphygmomanometer, comprising: pressure arteries and veins unit, piezo-electric drive units, control unit and pressure sensing cells. Pressure arteries and veins unit is used to contact testee. Piezo-electric drive units connection pressure arteries and veins unit is to carry out pressurization and pressure release. Control unit is electrically connected piezo-electric drive units, and it indicates that piezo-electric drive units drop under stress and slows down pressure release speed when measuring region or diastolic pressure measurement region up to systolic pressure, and left when systolic pressure measures region or diastolic pressure measurement region in pressure because of decline and speed pressure release speed. Pressure sensing cells are electrically connected pressure arteries and veins unit and control unit, measure the pressure change in pressure arteries and veins unit to acquire a plurality of pressure point values, and each pressure point value is sent to control unit. Therefore, this creation can be with the time needed for shortening amount measuring blood pressure, and then improves seeing for medical institutions and examine efficiency.一種電子血壓計，包括：壓脈單元、壓電驅動單元、控制單元及壓力感測單元。壓脈單元用來接觸受測者。壓電驅動單元連接壓脈單元以進行加壓及洩壓。控制單元電性連接壓電驅動單元，並指示壓電驅動單元在壓力下降達收縮壓量測區域或舒張壓量測區域時減緩洩壓速度，及在壓力因下降而離開收縮壓量測區域或舒張壓量測區域時增快洩壓速度。壓力感測單元電性連接壓脈單元與控制單元，其量測壓脈單元內的壓力變化來採集複數個壓力點數值，並將各壓力點數值傳送至控制單元。因此，本創作可以縮短量測血壓所需的時間，進而改善醫療單位的看診效率。
