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. 用于修改受试者的认知状态的便携式经皮电刺激(TES)施加器。般来讲，所述的便携式施加器被专门配置和适配为轻型化且可佩带式的，以用于传递能够引起或增强预定的认知效应的高强度TES。这些TES施加器可包括对电极和TES控制模块，所述TES控制模块包括处理器、定时器和波形发生器。TES控制模块适于在第电极和第二电极之间传递10秒或更长的双相电刺激信号，所述双相电刺激信号具有400Hz或更大的频率、大于10％的占空比、3mA或更大的强度、具有直流偏移。
