Abstract
A pressure sensor having a diaphragm having a boss with a pattern. The diaphragm having a boss may be regarded as a bossed diaphragm. The bossed diaphragm may have higher sensitivity than a flat plate diaphragm having the same area as the bossed diaphragm. The bossed diaphragm may incorporate a simple cross pattern that can further improve the sensitivity and linearity of a pressure response of the diaphragm at low pressures. Reduction of sharp edges and corners of the boss and its legs around the periphery of the diaphragm may reduce high stress points and thus increase the burst pressure rating of the bossed diaphragm.
