Wearable stochastic galvanic stimulation device
The present invention provides in part wearable devices for balance control. The wearable devices are capable of non-invasively monitoring and stimulating the wearer's vestibular system such that it produces postural responses. The wearable devices deliver low levels of electrical current to the vestibular system of a user to maintain balance. In one example, the wearable device is in the form of a pair of glasses.

one or more accelerometers positioned in the temples;
one or more gyroscopes positioned in the temples;
one or more magnetometers positioned in the temples;
one or more processors communicatively connected to the electrodes, the wireless transceivers, the accelerometers, the gyroscopes, and the magnetometers, the processor positioned in the temples, wherein the processors are configured to modulate a stimulation provided by the electrodes based on information provided by at least one of the accelerometers, the gyroscopes and the magnetometers; and
one or more batteries positioned in the temples;
wherein the one or more electrodes is configured to provide an electrical stimulation with an intensity of 0.01 to 1 mA, an increasing period of 1 to 60 seconds, a stimulation period of 2 to 30 minutes, a decreasing period of 1 to 60 seconds, and an inactive period of 5 to 240 minutes.
2. The device of claim 1 , wherein one or more of the accelerometers, gyroscopes, and magnetometers communicate with the one or more processors to send information relating to the device's speed, acceleration, orientation, location, and direction.
3. The device of claim 2 , wherein the one or more processors adjusts the level of the stimulation to the one or more electrodes to increase, decrease, or maintain electrode firing rate based on the received information.
4. The device of claim 1 , wherein the temple tips are curved inwards towards each other.
5. The device of claim 1 , wherein the one or more electrodes deliver stochastic electrical stimulation to a user's skin near the user's mastoid process to enhance postural response.
6. The device of claim 1 , wherein the device sends, stores, and receives signals from cloud storage.
7. The device of claim 1 , wherein the device sends, stores, and receives signals to an onboard non-transitory computer-readable storage media.
8. The device of claim 1 , wherein the one or more wireless transceivers are selected from the group consisting of: Bluetooth transceiver, WiFi transceiver, near field communication transceiver, and mobile transceiver.
9. The device of claim 1 , wherein the one or more batteries are rechargeable.
10. The device of claim 1 , wherein the one or more batteries are removable.
11. The device of claim 1 , further comprising one or more inductive charging coils positioned in the glasses frame.
12. The device of claim 1 , further comprising corrective lenses or non-corrective lenses.
13. A system for galvanic vestibular stimulation, comprising:
a glasses frame, two temples having proximal and distal ends, connected at the proximal ends to the glasses frame, two temple tips positioned at the distal ends of the temples, one or more electrodes positioned in the temple tips, one or more wireless transceivers positioned in the temples, one or more accelerometers positioned in the temples, one or more gyroscopes positioned in the temples, one or more magnetometers positioned in the temples, one or more processors positioned in the temples, and one or more batteries positioned in the temples; and
one or more non-transitory computer-readable media with instructions stored thereon;
wherein the instructions, when executed by the one or more processors, determine speed, acceleration, orientation, location, and direction of the glasses frame based on information provided by at least one of the accelerometers, the gyroscopes and the magnetometers, and modulates a level of stimulation at the one or more electrodes; and
wherein the one or more electrodes is configured to provide an electrical stimulation with an intensity of 0.01 to 1 mA, an increasing period of 1 to 60 seconds, a stimulation period of 2 to 30 minutes, a decreasing period of 1 to 60 seconds, and an inactive period of 5 to 240 minutes.
14. The system of claim 13 , wherein the one or more electrodes deliver stochastic electrical stimulation to a user's skin near the user's mastoid process to enhance postural response.
15. The system of claim 13 , wherein the one or more wireless transceivers are selected from the group consisting of: Bluetooth transceiver, WiFi transceiver, near field communication transceiver, and mobile transceiver.
16. The system of claim 13 , wherein the one or more batteries are rechargeable or removable.
