摘要：
A non-invasive blood pressure sensor comprises tissue-matable sensor bodies that include a first light-source-and-photodetector pair disposed on one of the sensor bodies in a pre-determined spatial relationship for a proximal anatomical location, and a second light-source-and-photodetector pair disposed on one of the sensor bodies in a pre-determined spatial relationship for a distal anatomical location. The sensor bodies may be mounted on a support structure acting as a jig for aligning and/or spacing them. A controller receives signals from the photodetectors and calculates blood pressure by identifying peaks and valleys in time series data obtained from the photodetectors, and calculating the subject's blood pressure based on differences in time between: (i) a proximal peak detected by the first light-source-and-photodetector pair and a distal peak detected by the second light-source-and-photodetector pair； and (ii) a proximal peak detected by the first light-source-and-photodetector pair and a distal valley detected by the second light-source-and-photodetector pair.
