Screen-Printed Magnetic Electrode

What is it? It is a graphite screen-printed electrode coupled with a screen-printed bonded magnet (NdFeB particles dispersed in a thixotropic carbon ink) with 3 mm ∅, 56 ± 6 μm thickness. Scope The magnetic screen-printed electrode is a compact, portable, cheap, and disposable alternative to various accessories have been developed aiming to attract MNPs on the electrode surface, such as magnetic electrode shafts, electrochemical cells integrating (electro)magnets, magnetic stickers, etc. Investigation In the study parameters as the composition of the NdFeB/ink blend, the thickness and the pattern (compact or hole-engraved) of the printed magnet, and the thickness of the substrate were investigated by both experimental and theoretical studies. Results The performance is enhanced if a void round area is created in the center of the magnet to introduce a further area of strong field gradient. This pattern allows the development of stronger attracting forces to MNPs, higher MNPs loading, a
