A mobile blood pressure device and a blood pressure measurement method are disclosed. The mobile blood pressure device comprises a pulse signal sensor, a chest-lead electrocardiography signal sensor, and a blood pressure calculating unit. The pulse signal sensor senses a pulse signal. The chest-lead electrocardiography signal sensor at least comprises a finger electrode, a non-contact chest electrode, and an active electrode circuit. The finger electrode is used for contacting a finger, and the non-contact chest electrode forms a coupled capacitor via an inserted cloth. The active electrode circuit senses a chest-lead electrocardiography signal via the finger electrode and the non-contact chest electrode. The blood pressure calculating unit calculates a blood pressure according to the pulse signal and the chest-lead electrocardiography signal.一種行動式血壓裝置及血壓量測方法。行動式血壓裝置包括脈波訊號感測器、胸導程心電訊號感測器及血壓計算單元。脈波訊號感測器感測脈波訊號。胸導程心電訊號感測器至少包括指部電極、非接觸式胸部電極及主動式電極電路。指部電極用以接觸指部,而非接觸式胸部電極用以經隔離物與胸部形成耦合電容。主動式電極電路經指部電極及非接觸式胸部電極感測胸導程心電訊號。血壓計算單元根據脈波訊號及胸導程心電訊號計算血壓值。10...行動式血壓裝置110...脈波訊號感測器120...胸導程心電訊號感測器122...指部電極124...非接觸式胸部電極128...主動式電極電路130...血壓計算單元140...顯示單元S1...脈波訊號S2...胸導程心電訊號S3...血壓值
