Abstract

The invention relates to a capacitive textile electrode for capacitively measuring electric signals, in particular biological signals, wherein the electrode has a multilayer structure which has at least two electrically conductive layers which are composed of a textile material and has at least one insulation layer which is arranged between the at least two electrically conductive layers, characterized by one, several or all of the following features: a) the at least two electrically conductive layers are mechanically connected to one another and/or to the insulation layer by adhesive bonding, b) at least one several or all of the electrically conductive layers have a prefabricated electrically conductive textile sheet material and/or a prefabricated textile EMC shielding material or comprise the same, c) at least one, several or all of the electrically conductive layers are in the form of textile pieces which have been cut by laser beam, d) at least one amplifier electronics system for amplifying the electrical signals emitted by the capacitive electrode is integrated into the multilayer structure of the capacitive electrode. The invention further relates to the use of prefabricat…
