Patent ID: 8690785

Claim:
An apparatus for determination of blood pressure, comprising: a transceiver; at least one sensor for blood pressure determination with a flexible housing adapted to be attached to the body of a living being proximate to an artery, an electronic circuit for wireless coupling a pressure signal to the transceiver in accordance with the blood pressure in the artery, wherein the flexible housing is a flexible foil having an adhesive on a lower surface thereof and which supports each of mutually isolated metal sheets on the lower surface in such a way that when the flexible housing is attached to the body, the mutually isolated metal sheets form the plates of a capacitor with at least the artery as a dielectric between the plates, and an inductor placed into the flexible housing and connected to the mutually isolated metal sheets such that the capacitor, formed when the flexible housing is attached to the body, and the inductor are interconnected to form a resonant circuit as the electronic circuit, the transceiver adapted for wireless coupling to the electronic circuit of the at least one sensor for generation of the pressure signal in accordance with the blood pressure in the artery; and a processor connected to the transceiver for reception of the pressure signal and adapted to estimate systolic and diastolic pressure based on the signal.
