Figure: Morphology evolution of the Ti–Me films attending to the different structural zones identified: (a) Ti–Al system, (b) Ti-Cu system, (c) Ti-Ag system, and (d) Ti–Au system. The morphology of the pure Ti and Me metallic thin films are included to be used as reference.

New publication on Me-Doped Ti–Me intermetallic thin films used for dry biopotential electrodes
A new type of nanostructured titanium-based thin film reveals improved biopotential sensing performance and overcoming several of the limitations of conventional gel-based electrodes and exhibiting increased biocompatibility over Ag/AgCl based electrodes. Four different Ti–Me (Me = Al, Cu, Ag, or Au) metallic binary systems were prepared by magnetron sputtering. The morphology of the resulting Ti–Me systems was found to be dependent on the chemical composition of the films, specifically on the type and amount of Me. The existence of crystalline intermetallic phases or glassy amorphous structures also revealed a strong influence on the morphological features developed by the different systems.
