Abstract

Sensing patch systems are disclosed herein. A sensing patch system includes a flexible substrate and a sensor node. The flexible substrate includes one or more substrate sensors configured to provide sensor data, one or more substrate conductors electrically coupled to a corresponding substrate sensor to conduct the sensor data provided by the corresponding substrate sensor, and a node interface. The sensor node includes a substrate interface configured to receive the node interface of the flexible substrate. The sensor node is configured to receive the sensor data provided by the substrate sensors, process the sensor data, and communicate the processed sensor data to a remote device.

First claim

The invention claimed is:

1. A sensing patch system comprising:
a flexible substrate comprising (i) one or more substrate sensors configured to provide sensor data, (ii) one or more substrate conductors, wherein each substrate conductor is electrically coupled to a corresponding substrate sensor to conduct the sensor data provided by the corresponding substrate sensor, and (iii) a node interface, wherein each of the substrate conductors includes a terminal end located at the node interface; and
a sensor node comprising a main body having a door and a substrate interface configured to receive the node interface of the flexible substrate, wherein the sensor node establishes electrical contact with each of the terminal ends of the substrate conductors when the node interface is received by the substrate interface,
wherein the door of the sensor node is pivotable relative to the main body between (i) an open position to permit the substrate interface of the sensor node to receive the node interface of the flexible substrate and (ii) a closed position to secure electrical contact between node contacts of the node sensor and each of the terminal ends of the substrate conductors,
and wherein the sensor node is further configured to receive the sensor data provided by the sensors, process the sensor data, and communicate the processed sensor data to a remote device.

2. The sensing patch system of claim 1 , wherein (i) the flexible substrate includes a first surface that is configured to contact a subject and a second surface that faces away from the first surface and (ii) the substrate conductors are formed on the second surface.

3. The sensing patch system of claim 2 , wherein (i) the one or more substrate sensors include a first electrode formed on a first sensor pad of the second surface and a second electrode formed on a second sensor pad of the second surface and (ii) each of the first and second sensor pads are foldable onto the first surface such that the first and second electrodes face in the same direction as the first surface.

4. The sensing patch system of claim 3 , wherein the first surface of the flexible substrate includes an adhesive layer configured to adhere to the subject when the sensing patch system is applied to the subject and each of the first and second sensor pads are adhered to the adhesive layer when folded onto the first surface.

5. The sensing patch system of claim 3 , wherein (i) the flexible substrate includes a cutout extending through the first and second surfaces and (ii) the sensor node is configured to be received by the cutout such that the sensor node directly contacts the subject when the sensing patch system is applied to the subject.

6. The sensing patch system of claim 5 , wherein (i) an adhesive region is formed on the second surface and (ii) the sensor node adheres to the adhesive region when received by the cutout of the flexible substrate.

7. The sensing patch system of claim 6 , wherein the adhesive region is formed around the cutout of the flexible substrate.

8. The sensing patch system of claim 5 , wherein (i) the one or more substrate sensors include a third sensor and (ii) the third sensor includes an electrical trace that extends around the cutout of the flexible substrate.

9. The sensing patch system of claim 8 , wherein the third sensor provides a breathing sensor configured to provide data indicative of respirational activity of the subject.

10. The sensing patch system of claim 5 , wherein the sensor node includes (i) at least one node sensor configured to provide node sensor data and (ii) the at least one node sensor includes a subject interface that extends outwardly from the cutout of the flexible substrate when the sensor node is received by the cutout of the flexible substrate.

11. The sensing patch system of claim 10 , wherein (i) the sensor node a projection that extends outwardly from the main body and (ii) the subject interface of the at least one node sensor is positioned at least partially in the projection to contact the subject when the sensor node is received by the cutout of the flexible substrate and the sensing patch system is applied to the subject.
