In addition to the equations used for the pressure sensor, one must take in consideration the buckling phenomena that might happen in the case of compressive stress. Because of the negative influence in the case of clock feedthrough and current leakage, the differential path technique is used, so the pressure sensor is divided into two parts. 0000003334 00000 n When this conductor is pulled to the right or left as shown below, the length increases and the cross-sectional area decreases.

A pressure sensor is a device equipped with a pressure-sensitive element that measures the pressure of a gas or a liquid against a diaphragm made of stainless steel, silicon, etc., and converts the measured value into an electrical signal as an output. 13.7. 45 MPa. /F3 14 0 R The sensor is designed to give Q-factor above 1000 at the pressures below 1 mbar and static capacitance of few pF. Pressure sensors are used to directly measure pressure, as in a microphone or hydrophone, or can be used to indirectly measure variables such as altitude, speed of fluid/ gas flow, calibration, etc. /F1 13 0 R /MediaBox [0 0 595.32 841.92] /XObject /Group /Group /CS /DeviceRGB They can cover a large three-dimensionally shaped surface area and detect pressure without reducing wearing comfort.

There are sensors that measure the absolute pressure and those that measure the pressure relative to atmospheric pressure or a specified pressure. Biocompatibility of parylene also provides advantages for integration into the host environment.

Touch-mode sensors have a linear output region and also a built-in overpressure stop to prevent diaphragm breakage during high pressure transients.
