Abstract

An Internet of Thing (IoT) device includes a head portion; an elongated stress sensor coupled to the head portion, the stress sensor coupled to a surface; a processor coupled to the stress sensor; and a wireless transceiver coupled to the processor.

Claims

1. An Internet of Thing (IoT) device, comprising:

a head portion;

an elongated stress sensor in an elongated body extending from the head portion, the stress sensor coupled to a surface;

a processor in the head portion or elongated body coupled to the stress sensor; and

a wireless transceiver in the head portion or elongated body coupled to the processor.

2. The IoT device of claim 1, wherein the elongated body encloses the stress sensor and coupled to the head portion to form a bolt.

3. The IoT device of claim 1, comprising a washer coupled to the head portion, wherein the body comprises a threaded portion positioned through an aperture of the washer and wherein the stress sensor is positioned in a core of the threaded portion or adjacent a washer.

4. The IoT device of claim 1, wherein sensor data is provided to a crowd as a game for one or more reasons explaining sensor data.

5. The IoT device of claim 1, wherein the processor and the sensor are in a recessed chamber of a bolt and the wireless transceiver comprises a mesh network transceiver where data hops from one transceiver to another transceiver to extend communication range.

6. The IoT device of claim 1, comprising a camera in the head portion or the elongated body and coupled to the processor.

7. The IoT device of claim 1, comprising an electronic nose or electronic tongue in the head portion or the elongated body and coupled to the processor for environmental detection.

8. The IoT device of claim 1, comprising a cloud based image processing system running code to receive images from the camera and code to recognize an image.

9. The IoT device of claim 1, wherein the stress sensor is coupled to a bolt, a screw, a stud or a fastener.

10. The IoT device of claim 1, comprising a wireless mesh network coupled to the wireless transceiver to transfer data from node to node.

11. The IoT device of claim 1, comprising a bolt screw portion enclosing the sensor and coupled to the head.

12. The IoT device of claim 1, comprising an energy scavenging unit, a piezoelectric transducer, a solar cell, or a wireless energy capture unit to supply power to the processor.

13. The IoT device of claim 1, comprising code to analyze and predict stress.

14. The IoT device of claim 1, comprising code to analyze stress from all sensors and predict individual component failure for replacement prior to component failure.

15. A system, comprising:

a mesh network; and

a plurality of IoT devices mounted to a structure, each device having a head portion with an elongated body, a sensor in the elongated body to detect structural stress, a processor in the head portion or elongated body and directly connected to the sensor, and a wireless transceiver coupled to the mesh network.

16. The system of claim 15, wherein the stress sensor is coupled to a surface to detect stress or vibration associated with the surface.

17. The system of claim 15, comprising a camera in the head portion or the elongated body and coupled to the processor.

18. The system of claim 17, wherein the camera is in the head portion.

19. The system of claim 17, comprising a cloud based image processing system running code to receive images from the camera and code to recognize an image.
