Zusammenfassung: | PROBLEM TO BE SOLVED: To provide an electrode sheet that solves problems of conventional electrodes for sensors and that has excellent electric characteristics such as conductivity and electrostatic capacitance while achieving a lightweight electrode and high adhesiveness and durability in stretching property and bending property, and a vital sensor, a proximity sensor, a bioelectrical impedance measurement device using the electrode sheet.SOLUTION: A material for forming a conductive layer for a sensor is provided, which comprises: a thermosetting polyurethane polyurea resin (A) obtained by allowing an urethane prepolymer (a4) having an isocyanate group at a terminal thereof, obtained by the reaction of a diol compound (a1) having a carboxyl group, other polyol (a2), and an organic diisocyanate (a3), to react with a polyamino compound (a5); an epoxy resin (B) having two or more epoxy groups; a conductive filler (D); and an aziridine-based curing agent (E). The material has a gel fraction of 30 to 90 wt.%.SELECTED DRAWING: Figure 1
【課題】本発明は従来のセンサー用電極の問題点を克服し、軽量で延伸性、折り曲げ性などの高い接着性、耐久性を発現しながらも、導電性、静電容量などの電気特性に優れた電極シートと、その電極シートを用いた生体センサー、近接センサー、生体インピーダンス測定機の提供を目的とする。【解決手段】カルボキシル基を有するジオール化合物(a1)、他のポリオール(a2)および有機ジイソシアネート(a3)を反応させて得られる末端にイソシアネート基を有するウレタンプレポリマー(a4)と、ポリアミノ化合物(a5)とを反応させて得られる熱硬化性ポリウレタンポリウレア樹脂(A)と、2個以上のエポキシ基を有するエポキシ樹脂(B)と、導電性フィラー(D)と、アジリジン系硬化剤(E)とを含有し、ゲル分率が30〜90重量%であることを特徴とする、センサー用導電層形成材料。【選択図】図1 |
