LOST SALT AMOUNT MEASUREMENT DEVICE AND ALARM DEVICE

To increase the accuracy of measuring the concentration of salt in sweat.SOLUTION: A lost salt amount measurement device includes: a perspiration amount sensor for measuring the perspiration amount of a wearer; a substrate; a salt sensor having a pair of electrodes in the substrate; an electric conduction measurement unit for measuring the electric conduction between the pair of electrodes; and an operation unit for calculating the concentration of salt in sweat between the pair or electrodes on the basis of the electric conduction. The operation unit calculates the perspiration amount on the basis of information from the perspiration amount sensor, and calculates the lost salt amount of the wearer on the basis of the concentration of salt and the perspiration amount.SELECTED DRAWING: Figure 3 【課題】汗の塩分濃度の計測精度を向上させることができること。【解決手段】喪失塩分量計測装置は、装着者の発汗量を計測するための発汗量センサと、基板、及び基板に配置される一対の電極を備える塩分センサと、一対の電極の間の電気伝導度を計測する電気伝導度計測部と、電気伝導度に基づき、一対の電極の間にある汗の塩分濃度を算出する演算部を備え、演算部は、発汗量センサからの情報に基づいて発汗量を算出し、塩分濃度と発汗量に基づいて、装着者の喪失塩分量を算出する。【選択図】図３
