Abstract

Embodiments of the present disclosure relate to monitoring one or more physiological parameters of a subject using a multilayer wearable device. In an embodiment, a multilayer wearable device is configured to be attached to a subject. The multilayer wearable device comprises a substrate having multiple layers including a first portion connected to a second portion. The first portion has a first side and a second, opposite side. And the second portion has a first side and a second, opposite side. The first side of the first portion is configured to be attached to the subject and the second portion is arranged on top of the first portion such that the first side of the second portion is disposed adjacent the second side of the first portion. And, the wearable device includes one or more electrical components configured to sense a physiological parameter of the subject.

First claim

What is claimed is:

1. A multilayer wearable device configured to be attached to a subject, the multilayer wearable device comprising:
a single continuous substrate folded to form multiple layers, the substrate comprising a first portion and a second portion, the first portion having a first side and a second, opposite side, and the second portion having a first side and a second, opposite side;
wherein the first side of the first portion is configured to be attached to the subject and the second portion is arranged on top of the first portion such that the first side of the second portion faces the second side of the first portion;
a first electrical component arranged on the first portion of the substrate and configured to sense a physiological parameter of the subject;
a second electrical component arranged on the second portion of the substrate; and
a gel layer arranged between the first portion and the second portion,
wherein the first portion is porous to an active pharmaceutical ingredient such that the active pharmaceutical ingredient is able to transmit through the first portion to the subject.

2. The multilayer wearable device of claim 1 , wherein the second portion has a greater thickness than the first portion.

3. The multilayer wearable device of claim 1 , wherein the first portion is flexible and stretchable.

4. The multilayer wearable device of claim 1 , further comprising a first electrode arranged on the second side of the first portion and a second electrode arranged on the first side of the second portion, wherein the first electrode is not electrically connected to the second electrode, wherein the first electrode and the second electrode are configured to facilitate delivery of the active pharmaceutical ingredient to the subject via application of a voltage to the first electrode or the second electrode.

5. The multilayer wearable device of claim 1 , the gel layer further comprising particles configured to facilitate separation between the first portion and the second portion.

6. The multilayer wearable device of claim 1 , wherein the first electrical component comprises a capacitor arranged between the first portion and the second portion, wherein the capacitor facilitates measuring a pressure applied to the multilayer wearable device.

7. The multilayer wearable device of claim 1 , wherein the thickness of the substrate is less than or equal to approximately 10 micrometers.

8. The multilayer wearable device of claim 1 , the substrate comprising a third portion having a first side and a second, opposite side, wherein the third portion is arranged on top of the second portion such that the first side of the third portion is disposed adjacent the second side of the second portion.

9. The multilayer wearable device of claim 1 , wherein a width of an outer envelope of the first portion is greater than or equal to a width of an outer envelope of the second portion.

10. A method of manufacturing a multilayer wearable device configured to be attached to a subject, the method comprising:
arranging an electrical component on a single continuous substrate, wherein the electrical component is configured to sense a physiological parameter of the subject; and
folding the substrate to form the multilayer wearable device, wherein a first junction of the substrate separates a first portion and a second portion of the substrate, the first portion having a first side and a second, opposite side, and the second portion having a first side, and a second, opposite side; and
forming pores in the first portion, wherein the pores are porous to an active pharmaceutical ingredient such that the active pharmaceutical ingredient is able to transmit through the first portion to the subject,
wherein the first side of the first portion is configured to be attached to the subject, and the second portion is arranged on top of the first portion such that the first side of the second portion faces the second side of the first portion.

11. The method of claim 10 , further comprising disposing a gel on the second side of the first portion.

12. The method of claim 11 , the gel layer further comprising particles configured to facilitate separation between the first portion and the second portion.

13. The method of claim 10 , the method further comprising disposing a first electrode on the second side of the first portion and a second electrode on the first side of the second portion, wherein the first electrode is not electrically connected to the second electrode, wherein the first electrode and the second electrode facilitate delivery of an active pharmaceutical ingredient to the subject via application of a voltage to the first electrode or the second electrode.

14. The method of claim 10 , further comprising arranging the substrate so that a second junction separates the second portion and a third portion, the third portion having a first side and a second, opposite side, wherein the third portion is arranged on top of the second portion such that the first side of the third portion is disposed adjacent the second side of the second portion.

15. The method of claim 14 , further comprising disposing a gel on the second side of the second portion.

16. The method of claim 10 , wherein the second portion has a greater thickness than the first portion.
