Transdermal electrical stimulation devices for modifying or inducing cognitive state
First Claim
1. A method of modifying a subject'"'"'s cognitive state, the method comprising:
- activating a transdermal electrical stimulation (TES) applicator to deliver a pulsed, asymmetric, biphasic transdermal electrical stimulation having a frequency of 750 Hz or greater and an intensity of greater than 3 mA between a first electrode positioned on the subject'"'"'s skin on a temple or forehead region on a first side of the subject'"'"'s body and a second electrode on the subject'"'"'s skin on either the mastoid region of the first side of the subject'"'"'s body or on the subject'"'"'s neck; and
modifying the subject'"'"'s cognitive state by applying the biphasic transdermal electrical stimulation between the first and second electrodes for 10 seconds or longer.

Abstract
Portable transdermal electrical stimulation (TES) applicators for modifying a subject'"'"'s cognitive state. In general, the portable applicators described are specifically configured and adapted to be lightweight and may be wearable, and to deliver a high-intensity TES able to evoke or enhance a predetermined cognitive effect. These TES applicators may include a pair of electrodes and a TES control module comprising a processor, a timer and a waveform generator. TES control module is adapted to deliver a biphasic electrical stimulation signal of 10 seconds or longer between the first and second electrodes having a frequency of 400 Hz or greater, a duty cycle of greater than 10 percent, an intensity of 3 mA or greater, with a DC offset.
