  • Patent number: 11849792
    Abstract: A head-mounted device capable of more highly accurately measuring the physical conditions of a wearer as a worker that are necessary for estimating the possibility of heat stroke is provided. A head-mounted device includes an outer shell; a first channel as a gap between a head of a wearer and the outer shell; a second channel provided in the outer shell and connected to the first channel; a fan configured to send air from one of the first channel and the second channel to the other; a salinity sensor configured to measure salt concentration of sweat of the wearer; a first humidity sensor configured to measure an absolute humidity of intake air entering one of the first channel and the second channel; and a second humidity sensor configured to measure an absolute humidity of exhaust air exiting from the other of the first channel and the second channel.
