Abstract: A disposable self-powered biomedical sensor comprises a printed wet electrode on a substrate sheet. The wet electrode is provided with an electrolyte element to enhance the electrical contact with a surface to be measured. Moreover, a printed battery encapsulated in a hermetically sealed compartment is provided on the substrate sheet. The disposable self-powered sensor can be stored within an enclosure or a package which provides a proper atmosphere to prevent the drying of the electrolyte and prolong the shelf life of the sensors.

Abstract: A sensor for measuring biosignals is provided. The sensor comprises at least one electrode comprising: a substrate comprising a flexible non-conductive material; a conductive layer configured to transfer electrical signals; a gel layer configured to transfer electrical signals; and a barrier layer configured to protect the conductive layer and transfer electrical signals, wherein the barrier layer deposited on the substrate, the gel layer is deposited on the barrier layer so that the gel layer covers only a part of the barrier layer, and the conductive layer is deposited over an area of the barrier layer which is outside of an area of the barrier layer on which the gel layer is deposited.

Abstract: A biomedical sensor is provided. The biomedical sensor comprises a printed bio-potential electrode on the biomedical sheet sensor configured to provide an electrical contact with a surface to be measured, and a bi-stable printed electronic ink indicator provided on the biomedical sheet sensor and configured to indicate a loose contact of a bio-potential electrode operation by switching the color of the bi-stable indicator from a first color to a second color when a loose contact is detected.
