Abstract

A measurement device includes an electronic component device, a perspiration acceleration device, and a perspiration collection device. The perspiration acceleration device or the perspiration collection device is removably coupled to the electronic component device. The electronic component device is attached to a measurement site with a belt. A perspiration accelerating performance is made with respect to the measurement site with the perspiration acceleration device coupled to the electronic component device, and thereafter, the perspiration acceleration device is replaced with the perspiration collection device with the electronic component device attached to the measurement site, and the perspiration collection and measurement computation performance are made.

Claims
