Abstract: A photoelectric volume pulse wave sensor includes a light-emitting element and a light-receiving element. Electrodes constituting the light-emitting element or the light-receiving element are surface electrodes. At least one electrode among the electrodes is also used as an electrode that detects body motion.

Abstract: A biological condition diagnosis system includes, at least: an obtainer, a receiver, a preprocessor, a processor, and a diagnoser, for biological data. The obtainer obtains the biological data by a reflective photoelectric plethysmography sensor. The preprocessor optimally preprocesses the obtained biological data. The processor extracts a feature point from the preprocessed data. The diagnoser diagnoses a biological condition using machine learning, based on the extracted biological data.

Abstract: Disclosed is a reflective photoplethysmogram sensor comprising: a planar light emitting element and a planar light receiving element. The light emitting element and the light receiving element do not face each other in an up/down direction. The minimum distance h (mm) between at least a pair of the light emitting element and the light receiving element satisfies the following expression (1) (t×03.7)2≤h≤(t×1.3)2   Expression (1) where the minimum distance between the light emitting element and the light receiving element is h (mm), and a thickness of skin (epidermis+dermis) of a human body is t (mm), and the thickness is within the range 0.1 to 4 mm.
