Abstract
A pressure sensor is formed by separating two chambers by a movable member to which is coupled an amorphous metal material. The amorphous metal material is anchored at its other end to be subjected to differing amounts of stress in accordance with movement of the movable member due to pressure changes. The tensile stress applied to the amorphous member is electrically detected, e.g. by detecting the impedance characteristics of an electrical coil adjacent the amorphous member.
