  • Publication number: 20190167173
    Abstract: A fatigue degree determination device includes a fatigue degree determination unit. A first biological heart rate is acquired while a user is awake and at rest, based on a biological heart rate measured from the user. A second biological heart rate is acquired while the user is sleeping, based on the biological heart rate measured from the user. The fatigue degree determination unit determines a fatigue degree of the user, based on information read out from a storage medium, the first biological heart rate and the second biological heart rate. The storage medium stores the information in which a degree of change of one biological heart rate relative to the other biological heart rate of a biological heart rate while a person is awake and at rest and a biological heart rate while the person is sleeping and a fatigue degree are associated with each other.

  • Publication number: 20190019934
    Abstract: A thermoelectric conversion element has a flexible base sheet provided with a thermoelectric conversion layer, a first electrode and a second electrode provided at longitudinal ends of the thermoelectric conversion layer, and a heat insulation layer provided on a back surface of the base sheet at a position overlapping the first electrode. Therefore, when the thermoelectric conversion element is attached to a heat-generating component, the first electrode is raised in height by the heat insulation layer so as to be disposed farther away from the heat-generating component than the second electrode, and moreover, thermal conduction from the heat-generating component is suppressed by the heat insulation layer.
