  • Piezoelectric sensor for measuring pressure fluctuations
    Patent number: 9642539
    Abstract: The invention relates to a piezoelectric sensor for the improved measurement of mechanical variables such as force, pressure or measurement variables which are derived there from, particularly a PVDF film sensor having an improved sensitivity and temperature stability of the measurement signal for pressure measurements that vary in time and/or space, and for the one-and two-dimensional determination of the position and propagation velocity of pressure fluctuations and pressure waves with a single measurement sensor at a measurement location. A preferred field of application of the invention is the non-invasive, low strain and continuous measurement of the pulse rate and the systolic and diastolic blood pressure of humans and animals by determining the velocity and the signal form of the pulse waves.
