Stretchable electrode, manufacturing method of stretchable electrode, clothes for measuring biological information and method of measuring biological information
It is possible to provide a flexible electrode which does not cause skin degradation and skin inflammation caused by low molecular weight organic compounds, because it is excellent in washing durability, and is safe against skin due to deterioration of the electrode characteristics due to excessive long / high temperature drying and does not increase the cost.A stretchable electrode characterized by an area of 1 to 500 square cm and a thickness of 10 to 800 μ m in thickness, and an organic compound having a molecular weight of less than 2000 in the stretchable electrode is 1 to .It was found that the molecular weight of low molecular weight organic substances in the electrode was limited by the residual concentration of low molecular weight organic substances in the electrode, and the skin inflammation and skin inflammation were caused by the low molecular weight organic matter released from the electrode The concentration in the garment required from the release rate of the compound is managed.過剰な長時間・高温乾燥による樹脂の劣化による電極特性の低下やコストの増大を招くことがなく、洗濯耐久性に優れ、皮膚に対して安全で、低分子量有機化合物が原因となる皮膚かぶれ、皮膚炎症を発症しない伸縮性電極を提供する。 生体信号を測定するために皮膚に接触させる伸縮性電極として、面積が１～５００平方ｃｍ、厚さが１０～８００μｍであり、伸縮性電極中に含まれる分子量２，０００以下の有機化合物の含有量が１～５，０００ｐｐｍであることを特徴とする伸縮性電極を用いる。電極中の低分子量有機成分の残留濃度を制限することにより洗濯耐久性が向上すること、また、皮膚かぶれ、皮膚炎症の発症は電極中の低分子量有機成分の残留濃度そのものではなく、電極から徐々に放出される低分子量有機成分が原因であり、低分子量有機化合物の放出速度から求められる衣服内濃度を管理する。
