Abstract: An air-to-fuel (A/F) ratio sensor includes an insulation layer, two solid electrolyte layers made of a porous composite ceramic formed at both sides of the insulation layer, each solid electrolyte layer having an internal electrode layer on its boundary surface with the insulation layer and an external electrode layer on its other surface, and a diffusion barrier layer made of a porous composite ceramic, covering one of the external electrode layers. The A/F ratio sensor provides a linear A/F ratio signal by controlling only a pumping current for a reference partial pressure of oxygen. Thus, the A/F ratio sensor operates by a simpler driving principle, thereby simplifying the driving circuit thereof.

Abstract: Disclosed herein is an inertial sensor. The inertial sensor 100 according to preferred embodiments of the present invention includes: a membrane 110; a mass body 120 disposed under the membrane 110; a piezoelectric body 130 formed on the membrane 110 to drive the mass body 120; and trenches 140 formed by being collapsed in a thickness direction of the piezoelectric body 130 so as to vertically meet a direction in which the mass body 120 is driven. By this configuration, the trenches are formed by being collapsed in a thickness direction of the piezoelectric body 130 to provide directivity while retaining the rigidity of the piezoelectric body 130 to prevent a wave from being propagated in an unnecessary direction, thereby driving the inertial sensor 100 in a desired specific direction.
