PHYSICAL/BIOCHEMICAL SENSOR EMPLOYING AN ARRAY OF PIEZOELECTRIC MICRO-CANTILEVER RESONATORS OF SEVERAL SIZES, AND A PRODUCTION METHOD THEREFOR

摘要

The present invention discloses a physical/biochemical sensor using a multisized piezoelectric microcantilever resonator array which enables to quantitatively and simultaneously analyze a mass loading effect and a surface stress change effect and a manufacturing method thereof. In the physical/biochemical sensor using the multisized piezoelectric microcantilever resonator array, a plurality of piezoelectric micro-cantilever resonators having different sizes is arrayed so as to quantitatively and discriminately analyze a surface stress change as well as a sensor surface mass change induced by an adsorbed sensing-target material occurring in a sensing process. Thus, the mass loading effect and the surface stress change effect can be quantitatively and simultaneously analyzed.
