## Abstract

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.

## Claims

### Claim at position 1

1-10. (canceled)

### Claim 11

Device for humidifying a textile electrode comprising:
a first layer;
a second layer; and
a material capable of absorbing and retaining water;
wherein the material capable of absorbing and retaining water is located between the first layer and the second layer;
the first layer is impermeable to liquid water and water vapour; and
the second layer 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.

### Claim 12 (depends on 11)

Device for humidifying a textile electrode according to claim 11, wherein the first layer is a non-conductive and non-deformable layer.

### Claim 13 (depends on 11)

Device for humidifying a textile electrode according to claim 11, wherein the second layer is deformable.

### Claim 14 (depends on 11)

Device for humidifying a textile electrode according to claim 11, wherein the second layer is a microporous layer or a hydrophilic layer.

### Claim 15 (depends on 11)

Device for humidifying a textile electrode according to claim 11, further comprising a pocket, the material capable of absorbing and retaining water being contained in said pocket, said pocket is permeable to water in a direction extending inwards towards the material capable of absorbing and retaining water, and permeable to water vapour in the opposite direction thereto.

### Claim 16 (depends on 11)

Device for humidifying a textile electrode according to claim 11, wherein the second layer is comprised of at least one first portion and one second portion, the first portion being impermeable to liquid water and permeable to water vapour in a direction extending outwards from the material capable of absorbing and retaining water towards the outside of the device, the second portion being permeable to liquid water in both directions.

### Claim 17 (depends on 16)

Device for humidifying a textile electrode according to claim 16, wherein the second portion of the second layer comprises at least one perforation configured such that it is permeable to liquid water.

### Claim 18 (depends on 11)

Device for humidifying a textile electrode according to claim 11, further comprising a third layer having a thickness of at least 0.5 mm, said layer being located between the material capable of absorbing and retaining water and the first layer.

### Claim 19 (depends on 11)

System comprising:
a humidification device according to claim 11; and
a textile support comprising a conductive area;
wherein the textile support is connected to the humidification device such that the conductive area is in contact with the second layer.

### Claim 20 (depends on 16)

System comprising:
a humidification device according to any of claim 16; and
a textile support comprising a conductive area forming an electrode;
wherein the textile support is connected to the humidification device such that the conductive area is in contact solely with the first portion of the second layer.
