  • Abstract
    The pressure microsensor presented in this paper is based on a thin, elastic membrane, with boron implanted piezoresistive elements included, positioned in the maximum mechanical stress areas on the membrane. The pressure range for the developed sensors is in the 0divide400 mbar range, and this is the main novelty of this device. The optimized design and technological steps offer high efficiency, sensitivity and reliability to the developed pressure sensor.
