Tutorial 10: Electrical Stimulation in Biomedical Engineering Part 1 || COMSOL MULTIPHYSICS

In this video we show how to model Electrical Stimulation (ES) for biomedical engineering applications using Electric Currents Interface. The Electrical Stimulation simply means: applying electrical pulses through human skin to the nerves inside muscles to activate the muscles. Electrical Stimulation is commonly used for the therapy and recovery from impairment due to a trauma or disease. The electrodes attached to skin are the interface where the electric pulses are applied to human body. First, we explain the concepts of Electrical Stimulation, the modeling assumptions, and expected outputs. Then, we perform a stationary study to analyze the steady-state condition in which we use a fixed current as the stimulation pulse. We consider both bipolar and monopolar configurations for the electrodes as well as anisotropic properties of muscle tissues. We investigate the effectiveness of the stimulation through a parameter known as Activating Function. We also compare our results with the results of a research article to verify our model and simulation. This video is very useful to understand the concepts of Electrical Stimulation which can further be used for the development of functional electrical stimulation systems and neural engineering studies.
