Abstract

Provided herein is an integrated wireless patch comprising a contact layer, an electronics layer, and a battery layer. The contact layer is a substrate having gel cutouts. The electronics layer can be folded into contact with the contact layer. The battery layer can be folded into contact with the electronic layer. Further provided herein is a method of manufacturing a wireless integrated patch comprising folding a substrate comprising at least one cutout, at least one contact disk in communication with a surface of a patient through the cutout, and battery terminals, wherein the at least one cutout, the at least on contact, and the battery terminals are adaptable to be located in different layers after the substrate is folded.

Claims

1-23. -23. (canceled)

24. An integrated wireless patch comprising different layers, the patch comprising:

a contact layer comprising a substrate configured to come into contact with a surface of a user;

a battery layer disposed over the contact layer, wherein the battery layer comprises a battery;

an electronic layer disposed between the contact layer and the battery layer, wherein the electronic layer comprises at least one contact pad configured to sense a signal from the user; and

an adhesive spacer adaptable to be located between the contact layer and the electronic layer, wherein the adhesive spacer is configured to prevent signal leakage from the at least one contact pad.

25. The patch of claim 24 wherein the battery layer comprises battery terminal tabs.

26. The patch of claim 24 wherein the patch is adaptable to be assembled by positioning the electronic layer between the contact layer and the battery layer.

27. The patch of claim 24 wherein the contact layer comprises an electrode gel configured to facilitate communication between the surface of the user and the at least one contact pad.

28. The patch of claim 24 wherein the contact layer comprises one or more spiral cutouts configured to provide flexibility and reduce strain between the contact layer and the surface of the user.

29. The patch of claim 24 further comprising at least one antenna powered by the battery.

30. The patch of claim 24 further comprising at least one application-specific integrated circuit on the electronic layer.

31. The patch of claim 24 wherein the adhesive spacer is configured to add thickness to the patch, thereby protecting components on the electronics layer.

32. The patch of claim 24 wherein the electronic layer comprises conducting traces that relay the signal from the user sensed by the contact pads to an application-specific integrated circuit on the electronic layer.

33. The patch of claim 24 wherein each of the different layers are configured to be stacked above or below a different layer.

34. The patch of claim 24 wherein each of the different layers comprise a similar shape or size.

35. The patch of claim 24 wherein a center of each of the different layers substantially align.

36. The patch of claim 24 wherein prevention of signal leakage improves a quality of the signal sensed from each of the contact pad.

37. An integrated wireless patch comprising different layers, the patch comprising:

a contact layer comprising a substrate, wherein the contact layer is configured to come into contact with a surface of a user;

a battery layer disposed over the contact layer, wherein the battery layer comprises a battery; and

an electronic layer disposed between the contact layer and the battery layer, wherein the electronic layer comprises at least one contact pad configured to sense a signal from the user,

wherein each of the different layers are configured to be stacked above or below a different layer.

38. The patch of claim 37 wherein the battery layer comprises battery terminal tabs.

39. The patch of claim 37 wherein the patch is adaptable to be assembled by positioning the electronic layer between the contact layer and the battery layer.

40. The patch of claim 37 wherein the contact layer comprises an electrode gel configured to facilitate communication between the surface of the user and the at least one contact pad.

41. The patch of claim 37 wherein the contact layer comprises one or more spiral cutouts configured to provide flexibility and reduce strain between the contact layer and the surface of the user.

42. The patch of claim 37 further comprising at least one antenna powered by the battery.

43. The patch of claim 37 further comprising at least one application-specific integrated circuit on the electronic layer.

44. The patch of claim 37 wherein the electronic layer comprises conducting traces that relay the signal from the user sensed by the contact pads to an application-specific integrated circuit on the electronic layer.

45. The patch of claim 37 wherein each of the different layers comprise a similar shape or size.

46. The patch of claim 37 wherein a center of each of the different layers are substantially aligned.
