Temporary-tattoo for long-term high fidelity bio-potential recordings

Surface electromyography (sEMG) is a non-invasive method widely used to map muscle activation. For decades, it was commonly accepted that dry metallic electrodes establish poor electrode-skin contact, making them impractical for skin electromyography applications. Gelled electrodes are therefore the standard in sEMG with their use confined, almost entirely, to laboratory settings. Very recently we developed novel dry electrodes, exhibiting outstanding sEMG recording along with excellent user comfort. The electrodes (electronic tattoos) are realized using screen-printing of carbon and silver inks on a soft support. The conformity of the electrodes helps establish direct contact with the skin, making the use of a gel superfluous. The suitability of the electrodes for long-term and stable sEMG from different muscles was demonstrated and emphasizes the potential of the technology for many applications, such as brain-machine interfacing, muscle diagnostics, post-injury rehabilitation, and gaming.
