Abstract: A drive device includes a drive member, a light source, a marker, a detector, a signal processor and a strain controller. The drive member includes at least a material which generates a plasmon. The drive member generates strain in response to input energy. The marker is formed on a surface of the drive member. Strain occurs in the marker in accordance with a deformation of the drive member and the marker reflects or transmits light emitted from the light source. The detector detects a light intensity of light reflected from or transmitted through the marker. The signal processor calculates an amount of strain which occurs in the marker based on the light intensity. The strain controller controls an amount of strain of the drive member based on the amount of strain calculated by the signal processor.

Abstract: A strain sensor includes a light source, a marker which is disposed on a measuring object so that light from the light source is reflected by or transmitted through the marker, a detector which detects the intensity of the light from the marker, and a signal processor which calculates a strain amount based on the detected light intensity. The marker is a flat film including first and second media having different refractive indexes. The second medium is periodically arrayed in the first medium and exists simultaneously with the first medium on a plane parallel to the marker mounting surface. The maximum length of the second medium in a direction parallel to the mounting surface is shorter than the wavelength of the emitted light. The first and second media deform in response to load in a direction parallel to the mounting surface.

Abstract: A strain sensor includes a marker, detectors and a calculator. The marker is disposed on a surface of a measurement object and includes a strain body and surface plasmon generating particles. In the strain body, a strain is formed by a load. The surface plasmon generating particles are arranged in two directions which are parallel to two in-plane directions of a light receiving surface of the strain body. The first detector detects a spectral intensity of a light which has been reflected on the marker or has passed through the marker. The second detector detects absorption spectral peaks corresponding to the respective array directions of the particles from the spectral intensity. The calculator calculates the quantity of the strain of the marker based on a difference in wavelength of the two absorption spectral peaks.

Abstract: A structural color changeable material includes a strain body and surface plasmon generating particles. In the strain body, a strain is produced by an external pressure or an internal change. The surface plasmon generating particles generate surface plasmon and are contained in the strain body. The surface plasmon is generated by an incident light with a wavelength of 2400 nm or less. A mean particle size of the surface plasmon generating particles is equal to or less than the wavelength of the incident light. The surface plasmon generating particles are periodically arranged parallel to an in-plane direction of a reflection surface of the incident light.
