<p><P>PROBLEM TO BE SOLVED: To provide a sensor that readily and accurately determines the existence of chemical, biological and explosive compounds even with low concentration. <P>SOLUTION: The sensor device includes: an optical limiting structure including a metal layer with at least one metal particle having a size no greater than about 1,500 nanometer, and a phase-change material layer disposed adjacent at least a part of the metal layer, the phase-change material layer including a phase-change material, and a dendritic-metal layer disposed over at least a part of the phase-change material layer of the optical limiting structure, the dendritic-metal layer including an organic compound including branching chain amino acid groups attached to a metal structure. The optical limiting structure is configured to transition from a first optical state to a second optical state when the phase-change material is heated above a critical temperature, with transmittance of light at a predetermined wavelength through the optical limiting structure being lower at the second optical state of the optical limiting structure in relation to the first optical state of the optical limiting structure. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
