Abstract
One aspect of the subject matter described in this disclosure can be implemented in a device capable of estimating blood pressure. The device includes two or more sensors capable of performing measurements along an artery. The device also includes at least one processing unit coupled with the two or more sensors. The processing unit is capable of accessing one or more parameters including a stress-strain parameter based on a hydrostatic pressure calibration. The processing unit also is capable of determining a pulse transit time (PTT) based on the measurements, and determining a pulse wave velocity (PWV) based on the PTT. The processing unit is further capable of determining a blood pressure based on the PWV and the stress-strain parameter.
