Title:
DEVICE AND SYSTEM FOR MEASURING AMOUNT OF PERSPIRATION
Document Type and Number:
WIPO Patent Application WO/2023/195219
Kind Code:
A1
Abstract:
A perspiration amount measurement device 1 comprises: an air flow path 100 through which internal air IA flows; a first temperature/humidity sensor 20, which is located in a location open to the outside world and which measures the temperature and relative humidity of outside air OA taken in from a location on a side opposite to the wearer's side when viewed from the air flow path; a fan 30 that draws in the internal air IA in the air flow path 10 and discharges the internal air IA to the outside of the perspiration amount measurement device 1; and a second temperature/humidity sensor 40, which is located partway along the flow of the internal air IA generated by the operation of the fan 30 and which measures the temperature and relative humidity of the internal air IA. The perspiration amount measurement device 1 is attached to an edge 102 of a helmet 100, and can measure the amount of head perspiration more accurately than the prior art.
