Abstract: A method for cleaning a receptor layer of a surface stress sensor according to an embodiment of the present invention includes, in a surface stress sensor that detects a change in surface stress of a thin film, the change being caused by a receptor layer disposed on a surface of the thin film, causing at least a part of a surface region of the thin film to generate heat or supplying heat to the receptor layer from the outside of the surface stress sensor. This makes it possible to easily perform efficient cleaning of a surface stress sensor such as a sensor that performs detection using a piezoresistor while avoiding structural complications as much as possible.

Abstract: The present invention makes it possible to represent or synthesize any odor by separating the odor into a combination of a relatively small number of odors, similarly to separating a color into three primary colors. Since the “primary odors” corresponding to the primary colors have not yet been ascertained, the present invention provides a feasible method and apparatus in which, instead of presetting such fixed primary odors, the separation, synthesis, and the like can be performed by selecting a subset of odors from among a set consisting of a plurality of odors which subset or odors enables approximation of other odors as much as possible by mixture.
