Problems solved by technology

However, this technique only partially solves the problem of maintaining the delivery of water in liquid form, and does not solve the following problems: (i) uniformity of water vapor delivery to the skin; (ii) excess liquid between the moisture retainer and the conductive surface and (iii) management of prolonged measurements over 10 hours to 12 hours

Embodiment Construction

[0045] The invention relates to an electrode device comprising humidification means. The humidifying device includes a first layer, a second layer and a material capable of absorbing and retaining water. A material capable of absorbing and retaining water is located between the first and second layers. The second layer is the layer to be in contact with the conductive areas of the textile carrier, the first layer being on the opposite side of the device. The second layer in contact with the electrode is not permeable to liquid water from the material capable of absorbing and retaining water to the conductive region of the electrode, but is capable of permeating water vapor from the material capable of absorbing and retaining water to the conductive region of the electrode.

[0046] The first layer is located on the opposite side to be connected to the conductive area of ​​the textile carrier with respect to the material capable of absorbing and retaining water. The first lay...

Abstract

The present invention relates to a device for humidification of a textile electrode (1) comprising a first layer (3); a second layer (5); and a material (4) capable of absorbing and retaining water; in which the material (4) capable of absorbing and retaining water is situated between the first layer (3) and the second layer (5); the first layer (3) is impermeable to water and to water vapour; andthe second layer (5) is permeable to water in a direction running from the outside towards the material capable of absorbing and retaining water, and impermeable to water and permeable to water vapour in the opposite direction. The present invention also relates to a system comprising such a humidification device.

Description

technical field [0001] The present application relates to a device for automatically humidifying textile electrodes for ExG measurements. In particular, the present application relates to a device for humidifying a textile electrode and a system comprising the same. Background technique [0002] It is known to use textile electrodes to measure physiological parameters of the human body. [0003] However, the use of such textile electrodes is limited because their impedance is greater than that obtained by conventional methods (ie, when contacted with the skin through a gel). [0004] To compensate for this shortcoming, it is necessary to ensure the presence of moisture between the electrode and the skin to allow ionic conduction to occur between the two interfaces, resulting in sufficient conductivity to accurately detect signals generated by the human body. It is estimated that electrodes typically require 1 gram of water per day for optimal operation. [0005] In many a...
