Abstract

A number of variations may include a product including a substrate and a sensor device including a non-conductive layer and a conductive layer overlying the non-conductive layer wherein the sensor device is constructed and arranged to measure or monitor a variable comprising at least one of temperature, pressure, VOC concentration, state of charge, or state of health of a substrate.

First claim

What is claimed is:

1 . A product comprising:
a substrate; and a sensor device comprising a non-conductive layer and a conductive layer overlying the non-conductive layer wherein the sensor device is constructed and arranged to measure or monitor a variable comprising at least one of temperature, pressure, strain, volatile organic compound concentration, state of charge, or state of health of the substrate.

2 . The product of claim 1 wherein the substrate is a battery.

3 . The product of claim 1 wherein the substrate is a cooling fin.

4 . The product of claim 1 wherein the non-conductive layer comprises Polymethyl Methacrylate.

5 . The product of claim 1 wherein the conductive layer comprises graphite.

6 . The product of claim 1 wherein the sensor device is mechanically and thermally coupled to the substrate and the conductive layer is electrically isolated from substrate.

7 . The product of claim 1 wherein the sensor device further comprises a data acquisition module.

8 . The product of claim 7 wherein the data acquisition module is electrically coupled to an electronic control module of a vehicle.

9 . The product of claim 1 wherein the variable is measured via at least one of deformation of the non-conductive layer or substrate, or change in resistance of the conductive layer through at least one calculation.

10 . A method comprising:
providing a substrate; providing a non-conductive layer and overlying the substrate with the non-conductive layer; providing a conductive layer and overlying the non-conductive layer with the conductive layer to form a sensor device constructed and arranged to measure or monitor at least one variable comprising at least one of temperature, pressure, volatile organic compound concentration, state of charge, or state of health of the substrate.

11 . The method of claim 10 wherein the substrate is a battery.

12 . The method of claim 10 wherein the substrate is a cooling fin.

13 . The method of claim 10 wherein the non-conductive layer comprises Polymethyl Methacrylate.

14 . The method of claim 10 wherein the conductive layer comprises at least one of graphite or graphenes.

15 . The method of claim 10 wherein the sensor device is mechanically and thermally coupled to the substrate and the conductive layer is electrically isolated from the substrate.

16 . The method of claim 10 wherein the sensor device further comprises a data acquisition module.

17 . The method of claim 16 wherein the data acquisition module is electrically coupled to an electronic control module of a vehicle.

18 . The method of claim 10 wherein the conductive layer is spray-coated overlying the non-conductive layer.

19 . The method of claim 10 wherein the method further comprises attaching the sensor to the substrate through an attachment.

20 . A method comprising:
providing a substrate; providing a sensor device mechanically and thermally coupled to the substrate comprising a non-conductive layer and a conductive layer overlying the non-conductive layer constructed and arranged to measure or monitor at least one variable comprising at least one of temperature, pressure, volatile organic compound concentration, state of charge, or state of health of a substrate; and determining at least one of deformation of the non-conductive layer or substrate, or change in resistance of the conductive layer to provide measurement or monitoring of the at least one variable based on at least one calculation.
