Estimation of Whole-body Perspiration Using a Perspiration Measurement Helmet

The construction industry is known for a high number of casualties resulting from heat strokes. Heatstroke risk management at construction sites is therefore a crucial issue and needs to be addresses. One method to prevent heatstroke is to maintain the amount of water in the human body. To achieve this, it is essential to monitor the amount of perspiration of construction workers during working hours. In this study, we shifted focus toward helmets that are worn by workers at construction sites. The helmet that we developed can measure the amount of perspiration and we use the data to estimate whole-body perspiration.
