Wireless electrical stimulation system

1 . 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.

2 . The electrical stimulation apparatus of claim 1 , wherein the at least one electrical waveform is delivered to the set of muscle groups or nerve areas within the foot without the electrical waveform going through any part of the human body other than the foot.

3 . The electrical stimulation apparatus of claim 2 , wherein the at least one electrical waveform is delivered to the set of muscle groups or nerve areas within the foot without going through a heart of the human body.

4 . The electrical stimulation apparatus of claim 1 , wherein the two electrodes are integrated with an insole of a sandal, and the electrical stimulation unit is placed on an upper strap of the sandal.

5 . The electrical stimulation apparatus of claim 4 , wherein the insole includes a first conductive area and a second conductive area, wherein the first conductive area is insulated from the second conductive area, wherein the first electrode of the two electrodes is connected to the first conductive area, and wherein the second electrode of the two electrodes is connected to the second conductive area.

6 . The electrical stimulation apparatus of claim 5 , wherein the insole is substantially made of conductive rubber or conductive gel.

7 . The electrical stimulation apparatus of claim 5 , wherein the upper strap comprises one of the pair of first connectors that conductively connects to the first conductive area, and the other of the pair of first connectors that conductively connects to the second conductive area.

8 . The electrical stimulation apparatus of claim 7 , wherein the electrical stimulation unit is releasably connected to the pair of first connectors of the upper strap of the sandal.

9 . The electrical stimulation apparatus of claim 1 , wherein the structure that is wearable on the foot of the human body comprises one of a pair of sandals.
