Piezo-Electric Pressure Gauge by Differential Comparison with Vacuum
K Krishna das
The paper deals with a concept of piezoelectricity wherein extremely low pressures can be measured with use of piezoelectricity. Now all must be wondering what is so different about what we told. Here is it, when it comes to measuring higher pressures we have numerous instruments but when we have to measure very slight pressure difference, below the atmospheric pressure we have very limited gauges. Here is where we introduce our concept wherein you can measure very slight pressure variations by creating a pressure difference along the surface of the piezoelectric material.
