This invention relates to a device for humidifying a textile electrode (1) comprising a first layer (3)； a second layer (5)； and a material capable of absorbing and retaining water (4)； wherein the material capable of absorbing and retaining water (4) is located between the first layer (3) and the second layer (5)； the first layer (3) is impermeable to liquid water and water vapour； and the second layer (5) is permeable to liquid water in a direction extending inwards towards the material capable of absorbing and retaining water, and is impermeable to liquid water and permeable to water vapour in the opposite direction thereto. This invention further relates to a system comprising such a humidification device.本發明係關於一種用於對織物電極(1)進行加濕的裝置，包括：第一層(3)；第二層(5)；和能夠吸收和保持水的材料(4)；其中能夠吸收和保持水的材料(4)位於第一層(3)與第二層(5)之間；第一層(3)對液態水和水蒸汽不可透；第二層(5)在朝向能夠吸收和保持水的材料向內延伸的方向上對液態水可透，並且在與該方向相反的方向上對液態水不可透但對水蒸汽可透。本發明亦關於包括該加濕裝置的系統。
