PROBLEM TO BE SOLVED: To provide a gel sensor capable of accurately detecting a lactic acid value contained in sweat.SOLUTION: A gel sensor comprises: a collecting section 26 for collecting and conveying sweat 38 a first cavity 24 for storing the sweat 38 collected by the collecting section 26 and a gelatinous stimulation-responsive gel 23 for absorbing the sweat 38 stored in the first cavity 24 and reacting with lactic acid in the sweat 38. Through-holes 25 are formed in the collecting section 26, so that the sweat 38 moves through the through-holes 25 by capillarity. In the first cavity 24, the sweat 38 moves along the stimulation-responsive gel 23 between the through-holes 25 and the stimulation-responsive gel 23 by capillarity.SELECTED DRAWING: Figure 13COPYRIGHT: (C)2017,JPO&INPIT【課題】汗に含まれる乳酸値を精度良く検出できるゲルセンサーを提供する。【解決手段】汗38を回収して輸送する回収部26と、回収部26で回収された汗38を溜める第1空洞24と、第1空洞24に溜まった汗38を吸収し汗38の乳酸に反応するゲル状の刺激応答性ゲル23と、を備える。回収部26には貫通孔25が設置され、毛管現象により汗38が貫通孔25を移動する。第1空洞24では貫通孔25と刺激応答性ゲル23との間で毛管現象により汗38が刺激応答性ゲル23に沿って移動する。【選択図】図13
