摘要： Provided is a device for measuring an amount of perspiration of respective body parts of a person using a change in brightness, including: a temperature controller which raises temperature of a subject and induces sweating; a covering which is coated with a perspiration reagent and is in contact with a skin of the subject, wherein the perspiration reagent absorbs perspiration and changes its color in response to perspiration; a light irradiator which irradiates light to the covering; a reflected light collector which collects reflected light reflected from the covering; a brightness change measurer which measures a change in brightness of the reflected light collected by the reflected light collector; and a perspiration amount converter which converts the change in brightness to an amount of perspiration secreted from respective body parts of the subject.
