To propose an oral cavity sensor capable of analyzing tongue movements in more detail than before. In an oral cavity sensor () which is even provided with a sensor element () having a mechanical configuration capable of measuring each of external force components in three axis directions, the sensor element () can be protected by an elastic body (), and the whole of the elastic body () is covered with the coating film () made of a biocompatible material. Thereby, the sensor element () and the elastic body () can be safely attached in an oral cavity (MT) of a subject (EXA), and can measure each of the external force components in the three axis directions. As a result, on the basis of the external force components in the three axis directions, complicated tongue movements at the time of mastication or swallowing in the oral cavity (MT) can be analyzed in more detail than before.

Oral cavity sensor

A plurality of micro three-dimensional structure elements each having a movable structure fixed on a sacrifice layer, and fixation portions of the micro three-dimensional structure elements for the sacrifice layer are arranged into a film-like elastic body, and then the sacrifice layer is removed. Thus, a three-dimensional structure in which the individual micro three-dimensional structure elements are arranged independently of one another within the elastic body is manufactured.

Three-dimensional structure and its manufacturing method

Provided is a scanning near-field optical microscope capable of obtaining, in a highly sensitive manner, optical information having a spatial frequency higher than a spatial frequency corresponding to a wavelength of irradiation light. A scanning near-field optical microscopeaccording to the present invention includes: a light irradiating partfor emitting illumination light toward a samplea light receiving partfor receiving light; a microstructure for generating or selectively transmitting near-field light, the microstructure being disposed on at least one of an emission side of the light irradiating partand an incident side of the light receiving partand an ultrahigh-wavenumber transmitting mediumfor transmitting near-field light, the ultrahigh-wavenumber transmitting medium exhibiting anisotropy in permittivity or permeability.
