Abstract
Among the technical characteristics disclosed in this specification, the pulse wave sensor with one of the technical characteristic includes a construction to detect the pulse wave at a wrist (i.e., a construction to measure the pulse wave to be worn at the wrist). To be more concrete, the pulse wave sensor includes a measurement unit to measure the pulse wave, a power source unit to supply power to the measurement unit, a cable to connect between the measurement unit and the power source unit electrically, and a armlet type housing to contain the measurement unit, the power source unit, and the cable.

37. A pulse wave sensor comprising:
-
a first light sensor comprising; a first light emitting portion to emit light of a first emission intensity to a living body, and a first light receiving portion to receive returned light emitted from the first light emitting portion and penetrates the living body and to generate a first light receiving signal, a second light sensor comprising; a second light emitting portion to emit light of a second emission intensity weaker than the first emission intensity to the living body, and a second light receiving portion to receive returned light emitted from the second light emitting portion and penetrates the living body and to generate a second light receiving signal, and a processing circuit to acquire the pulse wave data based on a subtraction of the second light receiving signal from the first light receiving signal. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)
