Reducing the sensation of electrical stimulation with dry electrodes by using an array of constant current sources

The application of electrical current to stimulate nerves for functional and therapeutic purposes is well established [1,2]. Electrodes play a major role in the success of stimulation since the efficacy of intervention, avoidance of tissue injury and the associated discomfort are all determined by the stimulation waveform and type of electrode used [2]. Surface electrodes are the most commonly used electrode types in typical functional electrical stimulation (FES) application for correction of foot drop caused by damage to the brain or spinal cord.
