Development of a helmet-type wearable device capable of measuring perspiration during various activities

It is necessary to maintain the amount of moisture in the body to prevent heat stroke in construction site conditions under the scorching sun, and for that reason, it is important to ascertain the amount of whole-body sweating. This study focused on a helmet, which is mandatory gear at construction sites, and developed a helmet-type wearable device that is capable of measuring the amount of perspiration during various activities. In addition, the results of our investigation indicated the feasibility of measuring the amount of whole-body perspiration using this device.
