Abstract: A system and method for measuring blood pressure. In some embodiments, a system includes a speckleplethysmography sensor and a processing circuit. The system may be configured: to perform, using the speckleplethysmography sensor, blood flow measurements of a subject, and measurements of cuff pressure of a cuff worn by the subject, while the cuff pressure varies; and to calculate, from the blood flow measurements and the cuff pressure measurements, a first blood pressure.
