The blood pressure is earned recognition as a barometer of the health condition. Many blood pressure monitors use a cuff for measuring the pressure. These monitors are easy-to-use except for attaching the cuff. This paper proposes an estimation method of the diastolic blood pressure without a use of the cuff. The blood pressure is estimated by a pulse transmit time which is measured by a Doppler sensor and a pulse wave sensor. An experiment shows that the proposed method can estimate a diastolic blood pressure.
