Acceleration-Insensitive Pressure Sensor for Aerodynamic Analysis

This paper presents a method for preparing pressure sensor that is insensitive to acceleration along with experimental evidence of its efficacy in aerodynamic analysis. A literature review and preliminary studies revealed the undesirable effect on sensors are located moving elements, as evidenced by deviations from actual values piezoresistive made using MEMS technology. To address this, authors developed double-membrane geometry eliminated this imperfection; implementing two solo new geometry-designed was also proposed. Experimental tests suggested solution were conducted; these measurements presented here. The results indicated concept could be used measure dynamic pressures rotating objects order obtain measurement more reliable closer true derived analyses. published confirm reliability proposed device.
