Abstract
Apparatuses (e.g., devices, systems), and methods for transdermal electrical stimulation (TES). Apparatuses described herein can be self-contained, lightweight, and wearable. The apparatus may include a primary unit (TES stimulator) and an electrode portion that includes a first transdermal electrode and a second transdermal electrode and mates with the TES stimulator. The first electrode and secondary electrode are placed at two locations on the skin of a user, for example on the head and/or neck of a user. Electrical stimulation driven between the two electrodes may induce a cognitive effect in a user of the device.
