PROBLEM TO BE SOLVED: To provide a gel sensor capable of responsively sensing a lactic acid value by accelerating the reaction of the gel sensor to lactic acid included in a sweat.SOLUTION: The gel sensor comprises: a fibrous liquid-transportation part 28 for transporting a sweat 45 and a gelatinous stimulation-responsive gel 24 which absorbs the sweat 45 and is responsive to the lactic acid of the sweat 45. The liquid-transportation part 28 is installed inside the stimulation responsive gel 24 and comprises a first exposure part 28c where the liquid-transportation part 28 is partially exposed from the stimulation-responsive gel 24.SELECTED DRAWING: Figure 19COPYRIGHT: (C)2017,JPO&INPIT【課題】汗に含まれる乳酸によるゲルセンサーの反応を短時間にして応答性良く乳酸値を検出できるゲルセンサーを提供する。【解決手段】汗45を輸送する繊維状の液体輸送部28と、汗45を吸収し汗45の乳酸に反応するゲル状の刺激応答性ゲル24と、を備え、液体輸送部28は刺激応答性ゲル24の内部に設置され、液体輸送部28の一部が刺激応答性ゲル24から露出する第1露出部28cを有する。【選択図】図19
