Pressure detecting apparatus utilizing metal nanoparticles integrated structure, temperature sensing device, the pressure detection method, and the temperature detecting method

摘要

PROBLEM TO BE SOLVED: To provide a device and a method by which a pressure or a temperature in a local region may be measured.;SOLUTION: A pressure detecting device 100 comprises: a light source 101; a metal nanoparticle integrated structure 10 fixed on a substrate 20; a spectroscope 105; and an operation part 106. The metal nanoparticle integrated structure 10 includes beads with a size of micro order and metal nanoparticles immobilized on surfaces of the beads. Deformation of the beads caused due to a pressure changes a peak wavelength of an extinction spectrum of localized surface plasmon resonance caused in the metal nanoparticles. The pressure may be detected by utilizing this change of the peak wavelength. Similarly, deformation of the beads caused due to a temperature changes a peak wavelength of the extinction spectrum of the localized surface plasmon resonance, and hence, the temperature may be detected by utilizing this change of the peak wavelength.;COPYRIGHT: (C)2012,JPO&INPIT
