Embodiment Construction

[0029] In the various figures, the same reference numerals refer to the same or similar elements.

[0030] The polymer composition 1 according to the invention comprises a dispersed phase and a discrete phase. The dispersed phase comprises the polymer matrix 2 and ensures the mechanical structure of the composition, while the discrete phase comprises carbon nanotubes 3 and an adsorbent 4 selected from activated carbon particles and graphene microplatelets and ensures the polymer composition as well as the electrochemical interface and polymerization Electrical conduction of living tissue 9 in contact with composition 1 or electrode 6 .

[0031] The polymer matrix 2 can be a single polymer or a mixture of polymers. The polymer matrix is ​​typically composed of one or a combination of polymers, silicones, and hydrogels. The polymer matrix is ​​selected so as to have at least one or more of the following characteristics: flexible (hardness less than 65 Shore A), hydrophilic, pe...

Abstract

The invention relates to polymer compositions (1) comprising a polymer matrix (2) in which are dispersed carbon nanotubes (3) and adsorbent elements (4) selected from activated carbon particles and graphene nanoplatelets, as well as electrodes (6) comprising such compositions and electrical circuits (10) and devices comprising said electrodes.

Description

technical field [0001] The invention relates to an electrode of a device for non-invasive measurement of bioelectrical signals. [0002] In particular, the present invention relates to electrodes for devices for non-invasive measurement of bioelectrical signals that can be used without conductive glue and polymer compositions that can be used in such electrodes. . Background technique [0003] Electrodes for bioelectrical signal measurement can be used to detect and measure biological signals representing neural activity such as brain activity or muscle activity, for example. [0004] Such bioelectrical signals can be used, for example, to obtain electroencephalograms (EEG), electromyography (EMG), electrooculograms (EOG) or electrocardiograms (ECG), this list is not exhaustive, not only in the medical field, but also in the for more mainstream uses such as entertainment, personal monitoring or sports. [0005] "Wet" metal electrodes are known, eg Ag / AgCl electrodes. The...
