MEASUREMENT OF FLUID PRESSURE SUCH AS BLOOD PRESSURE

Circuitry and a sensor (2050) suitable for measuring blood pressure are described. The sensor (2050) of the present invention has a flexible piezoelectic material (1011, 1013, 1015) covering the opening of a chamber (1019). The chamber (1019) contains an electrically nonconductive, elastomeric mater...

More Information
Summary:Circuitry and a sensor (2050) suitable for measuring blood pressure are described. The sensor (2050) of the present invention has a flexible piezoelectic material (1011, 1013, 1015) covering the opening of a chamber (1019). The chamber (1019) contains an electrically nonconductive, elastomeric material (1017), and needs no pump to pressurize the chamber (1019). An array of sensors and circuitry for measurement of fluid pressure fluctuation in a flexible environment is given.
