Thin films of Au-Al2O3 for plasmonic sensing
Meira, Diana Isabela Faria; Domingues, Rui P.; Rodrigues, Marco S.; Alves, Eduardo; Barradas, Nuno P.; Borges, Joel Nuno Pinto; Vaz, F.This works reports on the development of nanoplasmonic thin films, composed of Au nanoparticles embedded in an Al2O3 matrix. The Au-Al2O3 thin films were deposited by magnetron sputtering, and then subjected to thermal treatments (in-air) to promote the growth of the Au nanoparticles. The change of the number of gold pellets placed in the erosion zone of the aluminium target, originated Au concentrations in the...
Dry electrodes for surface electromyography based on architectured titanium thi...
Rodrigues, Marco S.; Fiedler, Patrique; Küchler, Nora; Domingues, Rui P.; Lopes, Cláudia; Borges, Joel; Haueisen, Jens; Vaz, F.Electrodes of silver/silver chloride (Ag/AgCl) are dominant in clinical settings for surface electromyography (sEMG) recordings. These electrodes need a conductive electrolyte gel to ensure proper performance, which dries during long-term measurements inhibiting the immediate electrode’s reuse and is often linked to skin irritation episodes. To overcome these drawbacks, a new type of dry electrodes based on arc...
