Abstract
A blood pressure monitor includes a finger clip portion and a host portion. Multiple sensors are incorporated into the clip and obtain optical and mechanical response data from arteries in the finger. The clip urges the sensors against the skin of the finger without occluding blood flow. A processor in the host portion is operable to compute systolic and diastolic blood pressure based on extracted features from the sensed data and individual characteristics of the user. Related methods are also described.

A blood pressure monitor for computing the blood pressure of a patient comprising:
- an implement adapted to be placed against the skin of the patient and comprising an optical sensor and a mechanical response sensor;
- and
- a processor operable to compute the blood pressure of the patient based on data from the optical sensor and the mechanical response sensor.
A method for automatically determining blood pressure of a person comprising:
- obtaining optical data by placing an optical sensor against the skin of the person;
- obtaining mechanical response data by placing a mechanical response sensor against the skin without occluding a blood vessel under the skin;
- and
- computing on a processor the blood pressure of the person based on the optical data and the mechanical response data.
