A system for transducing arterial pressure includes a one-piece flexible cap configured to fit around a flexible piezo-electric sensor that is configured to alter an internal resistance upon deflection. The flexible cap includes a deflection wall configured to deflect towards the flexible piezo-resistive sensor in proportion to pressure applied by the artery. A pressure-transducing medium is sealed between the one-piece flexible cap and the flexible piezo-resistive sensor, such that deflection of the deflection wall towards the flexible piezo-resistive sensor causes proportional deflection of the flexible piezo-resistive sensor.一種用於轉換動脈壓力系統，包括經配置以環繞柔性壓電感測器裝配的單件式柔性蓋，柔性壓電感測器係經配置以依據偏轉而改變內部阻抗。柔性蓋包括偏轉壁，偏轉壁經配置以依據動脈所施加的壓力的比例而朝向柔性壓阻感測器偏轉。壓力轉換媒體係密封於單件式柔性蓋與柔性壓阻感測器之間，而使得朝向柔性壓阻感測器的偏轉壁的偏轉造成柔性壓阻感測器的成比例偏轉。
