PROBLEM TO BE SOLVED: To provide a humidifier for detecting a heart rate and a dehumidification program for detecting a heart rate which enable sufficient humidification.SOLUTION: The humidifier 100 for detecting a heart rate measures the potential difference signal between two electrodes provided at the steering portion of the humidifier or the potential difference signal between the electrode provided at a place separate from the steering portion and the electrode provided at the steering portion. The humidifier for detecting a heart rate calculates the polarity of the clothing of an subject coming into contact with the electrodes used in the measurement of the potential difference signal and/or the intensity of the potential difference signal from the measured potential difference signal. The humidifier for detecting a heart rate determines the hygroscopicity of the clothing of the subject on the basis of the calculation result and controls the intensity of humidification treatment to the contact parts of the electrodes with the subject on the basis of the determine result.COPYRIGHT: (C)2011,JPO&INPIT【課題】過不足なく加湿すること。【解決手段】心拍検出用加湿装置は、装置の操舵部に設けられた複数の電極のうち2つの電極間の電位差信号、又は、操舵部とは別の箇所に設けられた電極と操舵部に設けられた電極との間の電位差信号を測定する。そして、心拍検出用加湿装置は、測定した電位差信号から、電位差信号の測定に用いられた電極と接触した被験者の衣服の極性、及び/又は、電位差信号の強度を算出する。そして、心拍検出用加湿装置は、算出結果に基づいて被験者の衣服の吸湿性を判定し、判定結果に基づいて電極と被験者との接触部に対する加湿処理の強さを制御する。【選択図】図1
