Abstract

Skin covering elements utilize conductive regions including electrically conductive materials may be arranged to enable a user to actuate a capacitive touchscreen such as through a centrally arranged absorptive pad and/or laterally through a carrier. Embodiments directed to adhesive bandages and athletic tapes are provided. A method includes applying an adhesive bandage to a user and depressing a portion of the bandage against a surface of a capacitive touchscreen to control or operate a function of an electronic device. Conductive regions may be also arranged to communicate with an electrical interface, such as for resistive heating of skin of a user and/or providing communication with one or more sensors.

Claims

1. An adhesive bandage configured to adhere to skin of a user for covering a wound, the adhesive bandage comprising:

a continuous carrier including an inner face, an outer face, and a pressure-sensitive adhesive arranged along the inner face; and

an absorbent pad arranged along at least a central portion of the inner face and arranged to contact the wound of the user;

wherein an electrically conductive material is arranged in or on the absorbent pad to provide an electrically conductive path extending between a first face of the absorbent pad and a second face of the absorbent pad; and

wherein an electrically conductive material is arranged in or on the continuous carrier to provide an electrically conductive path extending between (i) skin of the user covered by the continuous carrier but not covered by the absorbent pad and (ii) a portion of the continuous carrier covering the absorbent pad.

2. An adhesive bandage according to claim 1, wherein the electrically conductive material arranged in or on the absorbent pad comprises at least one electrical conductor woven into or stitched into the absorbent pad.

3. An adhesive bandage according to claim 1, wherein the electrically conductive material arranged in or on the continuous carrier comprises at least one electrical conductor woven into or stitched into the continuous carrier.

4. An adhesive bandage according to claim 1, wherein the electrically conductive material arranged in or on the continuous carrier comprises an electrically conductive foil or mesh arranged in or in contact with the continuous carrier.

5. An adhesive bandage according to claim 1, wherein the electrically conductive material arranged in or on the absorbent pad and/or the electrically conductive material arranged in or on the continuous carrier comprises an electrically conductive polymer.

6. An adhesive bandage according to claim 1, wherein the pressure-sensitive adhesive is electrically conductive and has an AC impedance of no greater than 200 Ohms over a 2.5 cm×

2.5 cm area.

7. An adhesive bandage according to claim 1, wherein the electrically conductive material arranged in or on the absorbent pad comprises at least one electrical conductor coated onto the absorbent pad.

8. An adhesive bandage according to claim 1, wherein the electrically conductive material arranged in or on the continuous carrier comprises at least one electrical conductor coated onto the continuous carrier.

9. An adhesive bandage according to claim 1, wherein the pressure-sensitive adhesive comprises at least one dissolved or dispersed electrically conductive material.

10. An adhesive bandage according to claim 1, wherein the pressure-sensitive adhesive comprises a discontinuous adhesive layer, including discrete portions of adhesive that are not connected to one another.

11. An adhesive bandage according to claim 1, wherein the continuous carrier comprises an electrically conductive layer and a window-defining layer, wherein the window-defining layer defines a plurality of windows enabling access to the window-defining layer.

12. An adhesive bandage according to claim 1, wherein the continuous carrier comprises an electrically conductive matrix.

13. An adhesive bandage according to claim 1, wherein the continuous carrier comprises fabric.

14. An adhesive bandage according to claim 1, wherein the pressure-sensitive adhesive is electrically conductive and has an AC impedance of no greater than 100 Ohms over a 2.5 cm×

2.5 cm area.

15. An adhesive bandage according to claim 1, wherein the pressure-sensitive adhesive is electrically conductive and has an AC impedance of no greater than 50 Ohms over a 2.5 cm×

2.5 cm area.

2.5 cm area.

17. An adhesive bandage according to claim 1, wherein the continuous carrier comprises a first plurality of pores or holes, the electrically conductive material arranged in or on the continuous carrier comprises a second plurality of pores or holes, and pores or holes of the first plurality of pores or holes are aligned with pores or holes of the second plurality of pores or holes.

18. An adhesive bandage according to claim 1, further comprising an electrical interface configured for coupling to an electric power source to permit resistive heating.

19. An adhesive bandage according to claim 1, further comprising an electrical interface configured to provide electrical communication with one or more sensors.

20. A method for utilizing an adhesive bandage configured to adhere to skin of a user for covering a wound, the adhesive bandage comprising (A) a continuous carrier including an inner face, an outer face, and a pressure-sensitive adhesive arranged along the inner face, and (B) an absorbent pad arranged along at least a central portion of the inner face and arranged to contact the wound of the user, wherein an electrically conductive material is arranged in or on the absorbent pad to provide an electrically conductive path extending between a first face of the absorbent pad and a second face of the absorbent pad, and an electrically conductive material is arranged in or on the continuous carrier to provide an electrically conductive path extending between (i) skin of the user covered by the continuous carrier but not covered by the absorbent pad and (ii) a portion of the continuous carrier covering the absorbent pad;

the method comprising;

applying the adhesive bandage to at least one of skin or a fingernail of a user, thereby placing the skin or fingernail in conductive electrical communication with the electrically conductive path extending between the first face of the absorbent pad and the second face of the absorbent pad, and placing the skin or fingernail in conductive electrical communication with the electrically conductive path extending between (i) the skin of the user covered by the continuous carrier but not covered by the absorbent pad and (ii) the portion of the continuous carrier covering the absorbent pad; and

depressing a portion of the adhesive bandage against a surface of a capacitive touchscreen of an electronic device to control or operate at least one function of the electronic device.
