Wireless electrical stimulation system

An electrical stimulation apparatus for applying electrical stimulation to a foot of a human body, the apparatus comprising:

• an electrical stimulation unit configured to generate at least one electrical waveform,
• two electrodes operatively coupled to the electrical stimulation unit and configured to receive the at least one electrical waveform from the electrical stimulation unit, wherein the two electrodes are insulated from each other, and wherein the two electrodes are provided in a structure that is wearable on the foot of the human body, the structure being configured for providing electrical stimulation to the foot,
• wherein a pair of first connectors comprising male metal snap connectors are respectively disposed in the two electrodes, the pair of first connectors being disposed on an upper surface of a base of the structure wearable on the foot, and the pair of first connectors are capable of being in direct contact with the foot, with one male metal snap connector of the pair of first connectors disposed on a first electrode of the two electrodes and the other male metal snap connector of the pair of first connectors disposed on a second electrode of the two electrodes, and capable of being in direct contact with the foot, and
• a pair of second connectors comprising female metal snap connectors are respectively disposed on the electrical stimulation unit, and the pair of first connectors are removably attached to the pair of second connectors, and
• a remote controller configured for controlling the electrical stimulation unit by generating and transmitting one or more control signals, wherein the electrical stimulation unit includes a receiver configured for receiving the one or more control signals from the remote controller;
• wherein, in response to receiving the one or more control signals from the remote controller, the electrical stimulation unit generates the at least one electrical waveform and applies the at least one electrical waveform to the two electrodes;
• wherein the two electrodes are configured to deliver the generated at least one electrical waveform to a set of muscle groups or nerve areas within the foot that are electromagnetically coupled to the two electrodes;
• wherein at least one of the two electrodes is configured to be applied externally to the foot, and in contact with the foot;
• and
• wherein the one or more control signals cause the electrical stimulation unit to apply an electric potential to the two electrodes to provide an electrical stimulation to the set of muscle groups or nerve areas within the foot that are electromagnetically coupled to the two electrodes.
