Abstract

A shoe degradation sensor assembly includes a first sensor disposed in or proximate to a material layer of a shoe between a foot space and an outer surface of the shoe, and an electrical contact assembly operable to removably electrically connect the shoe degradation sensor assembly to a reader. The material layer changes in at least one physical property with degradation to the shoe, and the first sensor is configured to indicate the changing physical property of the material layer thereby indicating a degree of degradation to the shoe.

Claims

1. A shoe degradation sensor reader comprising:

a contact assembly configured to removably electrically couple to an LC (inductor-capacitor) tag disposed in or proximate to a material layer of a shoe, the material layer having at least one physical property that changes with degradation of the shoe, the LC tag having a resonant property affected by the at least one physical property of the material layer, the LC tag configured to indicate the at least one physical property of the material layer thereby indicating a degree of the degradation of the shoe;

a reader module operable to;

query the LC tag via the contact assembly; and

measure the at least one physical property of the material layer via the first sensor LC tag; and

a communication module operable to communicate the measurement of the at least one physical property of the material layer from the shoe degradation sensor reader to an electronic device.

2. The shoe degradation sensor reader of claim 1, wherein the communication module comprises a wireless communication module, operable to communicate with the electronic device in compliance with a wireless communications protocol including one or more of a Near-Field Communication (NFC) protocol, a radio frequency identification (RFID) protocol, a Bluetooth protocol, a Zigbee protocol, a Wi-Fi protocol, or a cellular communications protocol.

3. The shoe degradation sensor reader of claim 1, wherein the electronic device comprises a user interface device.

4. The shoe degradation sensor reader of claim 1, wherein the contact assembly comprises a removable mechanically compliant contact assembly.

5. The shoe degradation sensor of claim 1, wherein the contact assembly comprises at least one of an inductive coupling, a metallized hook-and-loop, one or more conductive adhesive electrical contacts, or one or more mechanically compliant electrical contacts.

6. The shoe degradation sensor reader of claim 1, wherein the resonant property of the LC tag is affected by a change in compression set in the material layer of the shoe.

7. The shoe degradation sensor reader of claim 6, wherein the resonant property comprises a resonant frequency, and wherein to query the LC tag, the reader module is operable to:

sweep a radio frequency energy source energizing the LC tag; and

observe at least one of a voltage peak or an impedance peak of the LC tag to identify the resonant frequency.

8. The shoe degradation sensor reader of claim 1, wherein the reader module is configured to be removably mounted in the shoe.

9. A shoe degradation sensor assembly comprising:

a material layer positioned between a foot space of a shoe and an outer surface of the shoe;

an LC (inductor-capacitor) tag in or proximate to the material layer of the shoe, wherein the material layer changes in at least one physical property with degradation of the shoe, the LC tag having a resonant property affected by the at least one physical property of the material layer, the LC tag being configured to indicate the at least one physical property of the material layer thereby indicating a degree of the degradation of the shoe; and

a contact assembly configured to connect the shoe degradation sensor assembly to a reader module that is operable to query the LC tag via the contact assembly, thereby measuring the at least one physical property of the material layer of the shoe.

10. The shoe degradation sensor assembly of claim 9, wherein the contact assembly comprises a removable mechanically compliant contact assembly.

11. The shoe degradation sensor assembly of claim 10, wherein the contact assembly comprises at least one of an inductive coupling, a metallized hook-and-loop, one or more conductive adhesive electrical contacts, or one or more mechanically compliant electrical contacts.

12. The shoe degradation sensor assembly of claim 9, wherein the resonant property of the LC tag is affected by a change in compression set in the material layer of the shoe.

13. The shoe degradation sensor assembly of claim 12, wherein the resonant property comprises a resonant frequency, and wherein to query the LC tag, the reader module is operable to:

sweep a radio frequency energy source energizing the LC tag; and

observe at least one of a voltage peak or an impedance peak of the LC tag to identify the resonant frequency.
