Wireless electrical stimulation system

1. A wireless electrical stimulation system for providing electrical stimulation to a foot of a human body, the system 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, the structure being configured for providing electrical stimulation to the foot, and

a wireless remote controller configured for wirelessly controlling the electrical stimulation unit by generating and transmitting one or more wireless control signals, wherein the electrical stimulation unit includes a wireless receiver configured for wirelessly receiving the one or more wireless control signals from the wireless remote controller;

wherein, in response to receiving the one or more wireless control signals from the wireless 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 wireless 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,

wherein the electrical stimulation unit is removably and directly connected to the two electrodes,

wherein the two electrodes are insulated from each other via an insulator that is located on a foot shaped base and divides the foot shaped base into two parts, wherein the electrical stimulation unit is integrated with an insole comprising the foot shaped base, wherein the foot shaped base consists of three sections: a first part, a second part, and the insulator, wherein the first part comprises one of the two electrodes and the second part comprises the other of the two electrodes, wherein the insulator is made of a material different from both a material of the first part and a material of the second part, and the insulator is a separate section in the foot shaped base distinct from the first part and the second part, and

wherein a pair of first connectors are each respectively disposed in the first part and the second part, and wherein a pair of second connectors are respectively disposed on one same side of the electrical stimulation unit, and the pair of first connectors are removably and directly connected to the pair of second connectors.

2. The wireless electrical stimulation system of claim 1 , wherein the electrical stimulation unit is capable of operating with at least two intensities or signal levels, and wherein the wireless remote controller has an intensity selector for selecting one of the at least two intensities or signal levels of operation for the electrical stimulation unit.

3. The wireless electrical stimulation system of claim 2 , wherein the intensity selector comprises an increase control and a decrease control.

4. The wireless electrical stimulation system of claim 1 , wherein the electrical stimulation unit is one of a plurality of electrical stimulation units, wherein the wireless remote controller comprises a display for indicating which one of the plurality of electrical stimulation units has been selected.

5. The wireless electrical stimulation system of claim 1 , wherein the wireless remote controller is a smart phone running an application.
