Title:
PERSPIRATION ANALYSIS DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/073797
Kind Code:
A1
Abstract:
This perspiration analysis device comprises: a wearable sensor that outputs an electrical signal derived from the electrolyte concentration and perspiration amount of sweat secreted from the skin of a wearer; a perspiration amount calculation unit (50) that calculates the perspiration amount of the wearer; an electrolyte concentration calculation unit (51) that calculates the concentration of electrolytes in the sweat of the wearer; a power supply control unit (53) that stops the supply of power to the wearable sensor, the perspiration amount calculation unit (50), and the electrolyte concentration calculation unit (51) when a power supply stop condition is established, and restarts the supply of power when a power supply stop period ends; and a stop period calculation unit (52) that calculates the power supply stop period on the basis of the electrical signal obtained by the wearable sensor.
