Abstract: Systems, devices and methods are provided for stimulating one or more nerves within a user. A system comprises a stimulator comprising an electrode configured for contacting the outer skin surface and an energy source coupled to the stimulator and configured to generate a plurality of positive voltage waves. The stimulator further comprises a bridge circuit configured to convert the positive voltage waves into alternating positive and negative voltage waves. The stimulator transmits the alternating positive and negative voltage waves transcutaneously from the electrode through the outer skin surface of the user to a selected nerve in the user adjacent to, or near, the target location. This allows the energy source to drive a full AC sine wave to the electrode using a single positive voltage rail, which reduces the complexity of the overall circuit, thereby reducing its overall size or footprint within the stimulation and its manufacturing cost.

Abstract: Systems, devices and methods are provided for stimulating one or more nerves within a user. A system comprises a stimulator comprising an electrode configured for contacting the outer skin surface at, or near, the target location and an energy source coupled to the stimulator and configured to generate at least one electrical impulse and to transmit the at least one electrical impulse transcutaneously from the electrode through the outer skin surface of the user to a selected nerve in the user adjacent to, or near, the target location. The energy source comprises a primary circuit board that includes a processor and a computer-readable data storage device storing program instructions that, when executed by the processor, the program instructions generate the electrical impulse, and a secondary circuit board removably coupled to the main circuit board.

Abstract: Systems, devices and methods are provided for stimulating one or more nerves within a user. A system comprises stimulator having an electrode configured for contacting the outer skin surface at a target location and an energy source coupled to the stimulator, The energy source is configured to generate at least one electrical impulse and to transmit the electrical impulse transcutaneously from the electrode through the outer skin surface of the user to a selected nerve in the user. In certain aspects, the systems and methods are particularly useful for non-medical purposes, such as reducing stress and anxiety, enhancing relaxation, improving sleep, energy, concentration and mood, increasing mental or physical performance, promoting mental health, recovery and wellness, generally improving the health and wellbeing of a user and/or for temporarily or permanently improving intelligence, learning capacity, memory retention, recall, mood, alertness and/or sleep efficiency in human beings.

Abstract: Systems, devices and methods are provided for delivering electrical impulses to bodily tissues for therapeutic purposes. A system for stimulating a nerve within a patient comprises a stimulator having an electrode configured for contacting the outer skin surface at, or near the target location and an energy source coupled to the stimulator, The energy source is configured to generate at least one electrical impulse and to transmit the electrical impulse transcutaneously from the electrode through the outer skin surface of the patient to a selected nerve in the patient adjacent to, or near, the target location. The system may include a wearable treatment device designed to optimize placement of the electrode at the target site.

Abstract: Systems, devices and methods are provided for delivering energy impulses (and/or fields) to bodily tissues for therapeutic purposes. A method for stimulating a nerve within a patient comprises detecting a target location on an outer skin surface of the patient adjacent to, near, or overlying, a selected nerve and positioning an electrode in contact with the outer skin surface at, or near, the target location. An electrical impulse is then applied from the electrode transcutaneously through the outer skin surface of the patient to the selected nerve to modulate the nerve. Detecting the target location of the underlying nerve allows the patient to position the nerve stimulator in the optimal position for stimulating the nerve.
