| Research Abstract |
We propose a strain sensor utilizing light scattered by a pair of nano-disks onto an elastomer sheet. It is known that a scattering spectrum of a nano-disk pair exhibit a dependency on the gap between the disks by local surface plasmon resonance. We formed nano-disk pairs with a diameter of 100 nm and a gap of 20 nm on an elastomer sheet. Spectrum measurements were performed when the elastomer sheet was being pulled. It was found that the shape of the scattering spectrum altered depending on the gap distance between the disks of the pair. It was confirmed that the strain can be measured by an optical way, offering wireless measurements of in situ strain. Because this sensor can be miniaturized to be sub-micron size,invasion to the embedding media can be decreased during the strain measurement.
