Abstract:
1. A mechanical deformation amount sensor, comprising: a sensor structure formed by one of a semiconductor substrate and an insulating substrate and integrally includes a deformation portion deformable, when a physical quantity to be detected is applied to the sensor structure, due to the physical quantity and a support portion for supporting the deformation portion; a first carbon nanotube resistance element provided on deformation portion to be mechanically deformed when the physical quantity to be detected is applied to said sensor structure; a second carbon nanotube resistance element provided on said support portion that is not deformed when the physical quantity to be detected is applied to said sensor structure; and a wiring pattern which is formed in a pattern on said sensor structure to be connected to said first carbon nanotube resistance element and said second carbon nanotube resistance element, wherein a voltage is applied to the first and second carbon nanotube resistance elements via said wiring pattern such that a change of electrical conductivity of said first carbon nanotube resistance element upon mechanical deformation of said first carbon nanotube resistance element is fetched as an electrical signal.
