Abstract
Neurostimulators for application of transdermal electrical stimulation (TES) and methods of using them for comfortably inducing a cognitive effect. The apparatuses described herein may include hardware, software and/or firmware components that are configured to safely and effectively apply high current intensity (e.g., using a high voltage source). These apparatuses may also include circuitry configured to deliver complex (e.g., ensemble) TES current waveforms that incorporate capacitive discharge current at selected portions of the delivered waveform to enhance user comfort. Methods of operating these devices to reduce capacitance buildup on the user's skin by delivering integrated capacitive discharging currents are also included.
