Electrodes for longterm monitoring of electrical impulses of heart or muscles in the form of temporary tattoos produced using an ink-jet printer. An international research group involving TU Graz presents this novel method in Advanced Science.
In the case of diagnostic methods such as electrocardiogram (ECG) and electromyography (EMG), gel electrodes are the preferred method of transmitting electric impulses from the heart or muscle. In clinical practice the frequently stiff and cumbersome electrodes noticeably restrict the mobility of patients and are not very comfortable. Because the gel on the electrodes dries out after a short time, the possibilities of taking measurements over a longer period using this kind of electrode are limited. Together with researchers from Instituto Italiano di Tecnologia (IIT) Pontedera, Università degli Studi in Milan and Scuola Superiore Sant’ Anna in Pisa, Francesco Greco from the Institute of Solid State Physics at TU Graz presents a novel method in Advanced Science which raises the transmission of electrical impulses from human to machine to the next level using printed tattoo electrodes.
Printed tattoo electrodes for long-term diagnostics
In the presented method, conducting polymers are printed on commercial temporary tattoo paper, thus producing single or multiple electrode arrangements. The external connections necessary for transmitting the signals are integrated directly in the tattoo. The tattoo electrodes are then applied to the skin like temporary transfer pictures and can hardly be felt by the wearer. Due to their extreme thinness of under one micrometre, the electrodes can be adapted perfectly to the uneven human skin, and can even be applied to parts of the body where traditional electrodes are not suitable, for instance the face. Francesco Greco, materials scientist at the Institute of Solid State Physics of TU Graz explains: “With this method we have managed to take a big step forward in further developing epidermal electronics. We are on a direct road to making an extremely economical and simple as well as versatile applicable system which has enormous market potential.” There is already concrete interest from international biomedical companies in the shared development of marketable products, Greco reports.
Personalising epidermal electronics
Another feature of the printer-created tattoo electrodes is that even a perforation of the tattoo, for instance through the growth of a hair, does not impair the conductivity of the electrode and the signal transmission. This is particularly relevant in the case of long-term applications because hair growth leads to inaccuracies in the results using traditional measuring methods. Flawless transmissions of up to three days were trialled in the tests of the Italian Austrian research group. This, explains Greco, facilitates the measurement of electrophysiological signals of patients and athletes over a longer period without restricting or influencing their normal activities. Electrodes of different sizes and arrangements could also be produced using the printer and individually adapted to the respective body part on which the measurement is to be carried out. Greco describes the ultimate goal of the research as follows: “We are working on the development of wireless tattoo electrodes with integrated transistor which would make it possible to both send and receive signals. Not only could we measure impulses using this method, but we could also stimulate body regions in a targeted way.”
