In this paper, a new type of vacuum microelectronic pressure sensor with “step cathode” and “curved cathode” is proposed and studied. Compared with the common vacuum microelectronic pressure sensor, the new sensor’s cathode emission current is greatly improved, making the output signal easy to detect, Enhanced capabilities and great advantages in improving output signal linearity, increasing sensitivity and extending range. In this paper, computer simulation results are drawn, and the fabrication of the step-array cathode and male plate pressure-sensitive films is briefly described. SEM photographs are also presented.
