ABSTRACT:
An accelerometer sensor is disclosed, utilizing a casing having a center axis, and a pressure sensitive element located at the bottom portion of the casing. A gel based medium is accommodated in the casing. Given that "x" denotes a positional deviation of the pressure sensitive element with respect to the center axis of the casing and that "h" denotes a height of the medium in the casing, the positional deviation (x) and the height (h) are set such that the value 2 x/h falls within a predetermined range and serves as a function of the anisotropic sensitivity ratio of the sensor.
