  • Publication number: 20150335875
    Abstract: Neurostimulator apparatuses for applying transdermal electrical stimulation that may be comfortably and securely worn on a variety of head shapes and sizes. The apparatuses and methods of using them described herein may be lightweight and wearable and configured to be attached at one end of a patient-facing surface of the apparatus by a cantilevered attachment so that an opposite end of the surface is free to float relative to the user's head. The cantilevered attachment may include two or more connectors spaced apart along an edge region of the patient-facing surface in an optimal arrangement to secure the neurostimulator in place. The neurostimulator apparatuses described herein may be secured to a separate or integral electrode assembly that may adhesively secure to the subject's head. The patient-facing surface of the neurostimulator may also be curved and twisted specifically for use at the temple/forehead region of a diverse population of potential users.

  • Publication number: 20150328461
    Abstract: Methods and apparatuses for amplitude modulation of all or a portion of an ensemble waveform to modify a user's cognitive state by transdermal electrical stimulation (TES). An ensemble current waveform may include a sequence of component biphasic current waveforms in which one or more parameters (such as frequency, current amplitude, percent duty cycle, and percent charge imbalance) vary between sequential component waveforms. These ensemble waveforms may be specifically configured to evoke a particular cognitive state when applied by TES. In particular, described herein are methods for applying amplitude modulation to all or a sub-set of the component waveforms in the ensemble waveform which may dramatically enhance the efficiency and effectiveness of the TES. Also described herein are methods and apparatuses for applying amplitude modulation to all or a portion of an ensemble waveform without truncating pulses of the component waveforms forming the ensemble waveform.

  • Publication number: 20150328467
    Abstract: Methods and apparatuses for controlling a wearable neurostimulator from a control apparatus. Described herein are methods and apparatuses for controlling the application of ensemble waveforms using a transdermal electrical stimulation by a neurostimulator having a processor. The controller may provide specifically configured commands to efficiently and accurately control the delivery of an ensemble waveform by the neurostimulator, wherein the ensemble waveform includes a sequence of component biphasic current waveforms in which one or more parameters (such as frequency, current amplitude, percent duty cycle, and percent charge imbalance) vary between sequential component waveforms particularly effective at evoking a desired cognitive state by TES.

  • Publication number: 20150238762
    Abstract: Described herein are methods for allowing a user to control a neuromodulator to modify a cognitive state being experienced by the user. The user may select a waveform ensemble from a hand-held user device having an interface, and the user may adjust the perceived intensity of the applied waveform ensemble with the user device while the waveform ensemble is being applied. Also described are methods of managing communication between the hand-held user device (such as a smartphone or the like) and a wearable neurostimulator. Methods of displaying and visually tracking and controlling the applied waveform ensemble are also described herein.

  • Publication number: 20150174403
    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.

  • Patent number: 9014811
    Abstract: Methods of modifying a subject's cognitive state by applying transdermal electrical stimulation (TES). In particular, described herein are methods of applying TES using a pair of electrodes each positioned at a particular location on the skin of the subject's head, or the head and neck, to evoke a predetermined cognitive state using a TES applicator. In particular, described herein are methods of enhancing attention, alertness, or mental focus or of enhancing a calm or relaxed mental state by applying high-intensity TES across electrodes positioned on the subject's temple and either the mastoid region or on the subject's neck. The subject may control the application directly and TES may be applied by a portable, including wearable, TES applicator.

  • Publication number: 20150088224
    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.
