Improvement of surface electromyography signal by nano-metals thin-film deposition

In this work, it was studied the possibility of improving the sEMG signal collected from surface electrodes placed on the skin by depositing metallic nanofilms of three metals (gold, silver, and aluminum) with three different thicknesses (100, 200, and 300) nm on EMG electrodes as an alternative to...

Description
Summary:In this work, it was studied the possibility of improving the sEMG signal collected from surface electrodes placed on the skin by depositing metallic nanofilms of three metals (gold, silver, and aluminum) with three different thicknesses (100, 200, and 300) nm on EMG electrodes as an alternative to the used wet gel. To increase the efficiency of electrodes in diagnosis. The properties of metallic nanofilms deposited on the electrodes have been studied by several techniques. X-ray diffraction shows good crystallization, especially for gold samples, and the crystal size increases with increasing sample thickness. Atomic force microscopy scans show that the roughness and size of the particles increase with increasing thickness. The thermal and electrical conductivity also increased, especially with gold plating, compared to the other two metals. The sEMG signal results show acceptable signal enhancement with reduced noise with nanoplating, especially with gold.
