Abstract

A sensor system includes an airbag engaged with the sole structure of an article of footwear, the airbag configured to compress and expand during use of the article of footwear, a force sensor engaged with the airbag and configured to detect force on the airbag based on changes in capacitance as the airbag compresses and expands, a port connected to the article of footwear and configured for communication with an electronic module, and one or more conductive leads extending from the force sensor to the port to place the force sensor in communication with the port. The system may be used with an article of footwear including an upper member at least partially defining a foot-receiving chamber and a sole structure engaged with the upper member.

Claims (31)

1 . A sensor system for use with an article of footwear, comprising:

an airbag configured to be engaged with a sole structure of the article of footwear, the airbag having a top portion and a bottom portion and configured to compress and expand during use of the article of footwear;

a force sensor comprising a first conductive member on the top portion of the airbag and a second conductive member on the bottom portion of the airbag, wherein the force sensor is configured to quantitatively detect changes in capacitance between the first conductive member and the second conductive member as the airbag compresses and expands with compression and expansion of the sole structure, and wherein the changes in capacitance are configured for use in quantitatively determining force on the airbag;

a port configured to be connected to the article of footwear and configured for communication with an electronic module; and

one or more conductive leads extending from the force sensor to the port to place the force sensor in communication with the port.

2 . The sensor system of claim 1 , further comprising the electronic module, wherein the electronic module is connected to the port and configured for receiving data from the force sensor through the port.

3 . The sensor system of claim 2 , wherein the electronic module is configured for receiving capacitance data from the force sensor indicating the changes in capacitance between the first conductive member and the second conductive member.

4 . The sensor system of claim 2 , wherein the electronic module is configured for receiving force data from the force sensor.

5 . The sensor system of claim 2 , wherein the electronic module is configured for transmitting the data to an external device.

6 . The sensor system of claim 1 , wherein the port is configured to be accessible within a cavity in the sole structure of the article of footwear.

7 . An article of footwear comprising:

an upper member at least partially defining a foot-receiving chamber;

a sole structure engaged with the upper member;

an airbag engaged with the sole structure, the airbag having a top portion and a bottom portion and configured to compress and expand during use of the article of footwear;

a force sensor comprising a first conductive member on the top portion of the airbag and a second conductive member on the bottom portion of the airbag, wherein the force sensor is configured to quantitatively detect changes in capacitance between the first conductive member and the second conductive member as the airbag compresses and expands with compression and expansion of the sole structure, and wherein the changes in capacitance are configured for use in quantitatively determining force on the airbag;

a port connected to the article of footwear and configured for communication with an electronic module; and

one or more conductive leads extending from the force sensor to the port to place the force sensor in communication with the port.

8 . The article of footwear of claim 7 , further comprising the electronic module, wherein the electronic module is connected to the port and configured for receiving data from the force sensor through the port.

9 . The article of footwear of claim 8 , wherein the electronic module is configured for receiving capacitance data from the force sensor indicating the changes in capacitance between the first conductive member and the second conductive member.

10 . The article of footwear of claim 8 , wherein the electronic module is configured for receiving force data from the force sensor.

11 . The article of footwear of claim 8 , wherein the electronic module is configured for transmitting the data to an external device.

12 . The article of footwear of claim 8 , wherein the sole structure comprises a cavity within the sole structure, and the electronic module is received within the cavity and connected to the port within the cavity.

13 . The article of footwear of claim 12 , wherein the cavity is located in a midsole of the sole structure.

14 . A sensor system for use with an article of footwear, comprising:

an airbag configured to be engaged with a sole structure of the article of footwear, the airbag having a top portion and a bottom portion and configured to compress and expand during use of the article of footwear, wherein the airbag includes internal fabric portions configured to maintain a shape of the airbag;

a force sensor comprising a first conductive member on the top portion of the airbag and a second conductive member on the bottom portion of the airbag, wherein the force sensor is configured to quantitatively detect changes in capacitance between the first conductive member and the second conductive member as the airbag compresses and expands with compression and expansion of the sole structure, and wherein the changes in capacitance are configured for use in quantitatively determining force on the airbag;

a port configured to be connected to the article of footwear and configured for communication with an electronic module; and

one or more conductive leads extending from the force sensor to the port to place the force sensor in communication with the port.

15 . The sensor system of claim 1 , wherein the port is configured to be located in a well within the sole structure of the article of footwear that is accessible for insertion or removal of the electronic module, and the port further comprises an interface connected to the one or more conductive leads and configured for connection to be removably connected to the electronic module within the well to place the force sensor in communication with the electronic module via the interface and the one or more conductive leads.

16 . The article of footwear of claim 7 , wherein the sole structure further comprises a well within the sole structure that is accessible for insertion or removal of the electronic module, and the port further comprises an interface connected to the one or more conductive leads and configured for connection to be removably connected to the electronic module within the well to place the force sensor in communication with the electronic module via the interface and the one or more conductive leads.

17 . The sensor system of claim 14 , wherein the port is configured to be located in a well within the sole structure of the article of footwear that is accessible for insertion or removal of the electronic module, and the port further comprises an interface connected to the one or more conductive leads and configured to be removably connected to the electronic module within the well to place the force sensor in communication with the electronic module via the interface and the one or more conductive leads.
