ABSTRACT:
Circuitry and a sensor suitable for measuring blood pressure is described. The sensor of the present invention has a flexible piezoelectric material covering the opening of a chamber. The chamber contains an electrically nonconductive, elastomeric material, and needs no pump to pressurize the chamber. An array of sensors and circuitry for measurement of fluid pressure fluctuation in a flexible environment is given.
