Analysis of electrode arrays for multichannel surface electromyography

Nowadays medical evaluation requires in each further step improvements in all the areas concerning engineering and materials. This applies to the application of electromyography and in specific to surface electromyography which is being used every day to evaluate muscular and neuromuscular diseases. In this field electrodes are used as interfaces to acquire the biopotential signals generated by muscles. The materials usually used in these electrodes are expensive. This fact can be a limitation factor for the applications that use a considerable number of them such as High Density surface electromyography. This thesis aims to evaluate using tests, parameters extraction, results analysis and performance comparison a set of different electrode arrays in order to evaluate the suitability of low cost material specifically stainless steel to perform the same tasks as other materials used in medical applications such silver or silver chloride electrodes
