The development and realization of a three-axial tactile force sensor capable of detecting the three components of an applied force is described. Recent investigations proved that the force sensor can be used as a micro-probe in dimensional metrology. The sensing element consists of a boss membrane fabricated by bulk silicon micro machining. The paper reports on a new design for the sensing elements (piezoresistors) and a new strategy to derive proportional the components of the applied force vector from the three signals.
