On Using Residual Voltage to Estimate Electrode Model Parameters for Damage Detection. [PDF]
IEEE Biomed Circuits Syst Conf, 2015 Current technology has enabled a significant increase in the number of electrodes for electrical stimulation. For large arrays of electrodes, it becomes increasingly difficult to monitor and detect failures at the stimulation site. In this paper, we propose the idea that the residual voltage from a biphasic electrical stimulation pulse can serve to ...
