Abstract

An apparatus for interfacing between tissues being stimulated is provided. The apparatus includes an electric source capable of generating an applied electric field across a region of tissue and/or a means for altering at least one electromagnetic characteristic of the region of tissue relative to the applied electric field and an interface component, such interface component creating an interface between the region of tissue and the applied electric field or the means for altering at least one electromagnetic characteristic of the region of tissue.

Claims

1. A stimulation apparatus comprising:

a cap configured to be worn on a head of a user;

a DC electric source coupled to the cap, the DC electric source capable of generating a DC electric field across a region of tissue; and

an ultrasound device coupled to the cap, the ultrasound device configured to generate a mechanical field across the region of tissue;

wherein the cap further comprises a material that acts as a bridging medium between the region of tissue and the electric source and/or ultrasound device.

2. The cap according to claim 1, wherein the electric source is embedded in the cap.

3. The cap according to claim 1, wherein the electric source is fastened to the cap.

4. The cap according to claim 1, wherein the electric source is placed on a surface of to the cap.

5. The cap according to claim 1, wherein the ultrasound device is embedded in the cap.

6. The cap according to claim 1, wherein the ultrasound device is fastened to the cap.

7. The cap according to claim 1, wherein the ultrasound device is placed on a surface of to the cap.

8. The cap according to claim 1, wherein the material matches acoustic properties of the mechanical field with the tissue.

9. The cap according to claim 1, wherein the material matches electromagnetic properties of the electric field with the tissue.

10. The cap according to claim 1, wherein the material matches acoustic properties of the mechanical field and electromagnetic properties of the electric field with the tissue.

11. The cap according to claim 1, wherein the material couples the electric field and the mechanical field before the fields are focused on the tissue.

12. The cap according to claim 1, wherein the DC source and the ultrasound device are adjustable within the cap relative to the tissue.

13. The cap according to claim 1, further comprising a control element.

14. The cap according to claim 13, wherein the control element controls a feature selected from the group consisting of:

number of uses and number of stimulations per session.

15. The cap according to claim 1, wherein the cap comprises multiple removable parts.

16. The cap according to claim 15, wherein at least one of the parts is disposable.

17. The cap according to claim 1, wherein the material is a fluid or gel.
