Abstract

An integrated circuit is described herein that includes a semiconductor substrate. First and second piezoresistive sensors are on or in the substrate where each have a respective sensing axis extending in first and second directions respectively parallel with a surface of the substrate, where the second direction is perpendicular to the first direction. A third piezoresistive sensor is on or in the substrate and has a respective sensing axis extending in a third direction parallel with the surface of the substrate and neither parallel nor perpendicular to the first and second directions.
