a ground-engaging outer surface;
an inner surface opposite to the ground-engaging outer surface; and
a sensor.

2. The track of claim 1 , wherein the sensor is disposed within elastomeric material of the track.

3. The track of claim 1 , wherein: the track comprises a plurality of projections projecting from the ground-engaging outer surface and the inner surface; and at least part of the sensor is located between the ground-engaging outer surface and the inner surface.

4. The track of claim 1 , wherein: the track comprises a plurality of projections projecting from the ground-engaging outer surface and the inner surface; and at least part of the sensor is located in a given one of the projections.

5. The track of claim 4 , wherein: the projections include traction projections projecting from the ground-engaging outer surface and wheel-contacting projections projecting from the inner surface; and the given one of the projections is a given one of the wheel-contacting projections.

6. The track of claim 5 , wherein: the wheels include a drive wheel for driving the track; the wheel-contacting projections include drive projections configured to engage the drive wheel; and the given one of the wheel-contacting projections is a given one of the drive projections.

7. The track of claim 1 , wherein: the wheels include a drive wheel for driving the track; and the sensor is configured to sense an interaction between the track and the drive wheel.

8. The track of claim 7 , wherein the interaction between the track and the drive wheel is slippage between the track and the drive wheel.

9. The track of claim 7 , wherein the interaction between the track and the drive wheel is a force between the track and the drive wheel.

10. The track of claim 1 , wherein the sensor is a wireless sensor.

11. The track of claim 1 , wherein the sensor is an optical sensor.

12. The track of claim 1 , wherein the sensor is a strain sensor.

13. The track of claim 1 , wherein the sensor comprises a wireless transmitter configured to wirelessly transmit a signal.

14. The track of claim 1 , wherein the sensor is configured to output a signal processable by a processing apparatus to perform an action related to the vehicle.

15. The track of claim 14 , wherein the action related to the vehicle is an action controlling the vehicle.

16. The track of claim 15 , wherein the action controlling the vehicle is an action controlling a tracked undercarriage of the vehicle that includes the track and the wheels.

17. The track of claim 16 , wherein the action controlling the tracked undercarriage is an action controlling power applied to the tracked undercarriage.

18. The track of claim 17 , wherein: the wheels comprise a drive wheel for driving the track; and the action controlling power applied to the tracked undercarriage is an action controlling power applied to the drive wheel.

19. The track of claim 16 , wherein: the tracked undercarriage is configured to drive the track in a plurality of drive modes that includes a friction drive mode and a positive drive mode; and the action controlling the tracked undercarriage is an action controlling in which of the drive modes the track is driven.

20. The track of claim 16 , wherein: the tracked undercarriage comprises a tensioner for tensioning the track; and the action controlling the tracked undercarriage is an action controlling the tensioner.

21. The track of claim 14 , wherein: the signal is a sensor signal; and the action related to the vehicle is issuance of a control signal to a component of the vehicle to control the component of the vehicle.

22. The track of claim 21 , wherein the component of the vehicle is a tracked undercarriage that includes the track and the wheels.

23. The track of claim 1 , wherein the sensor is configured to output a signal processable by a processing apparatus to convey information to a user.

24. The track of claim 23 , wherein the signal is processable by the processing apparatus to display the information to the user.

25. The track of claim 23 , wherein the signal is processable by the processing apparatus to convey the information to the user on a console of the vehicle.

26. The track of claim 23 , wherein the signal is processable by the processing apparatus to convey the information to the user on a device distinct from a console of the vehicle.

27. The track of claim 23 , wherein the information to the user is conveyed automatically in response to an event.

28. The track of claim 27 , wherein the event is indicative of potential failure of part of the track.

29. The track of claim 1 , wherein the sensor is configured to output a signal processable to generate information regarding the track.

30. The track of claim 29 , wherein the information regarding the track comprises information regarding usage of the track.

31. The track of claim 30 , wherein the information regarding usage of the track comprises information regarding a period of time that the track has been used.

32. The track of claim 29 , wherein the information regarding the track is directed to a manufacturer of at least one of the track and the vehicle.

33. The track of claim 32 , wherein the information regarding the track is useful in considering a warranty of the track.

34. The track of claim 1 , wherein the sensor comprises a piezoelectric element.

35. The track of claim 34 , wherein the piezoelectric element is configured to power the sensor.

36. The track of claim 1 , wherein the sensor comprises an induction antenna to power the sensor.

37. The track of claim 1 , wherein the sensor is a first sensor and the track comprises a second sensor.

38. A tracked undercarriage for traction of a vehicle, the tracked undercarriage comprising a plurality of wheels and the track of claim 1 .

39. A vehicle comprising the track of claim 1 .

40. An apparatus for use in respect of a vehicle comprising a track for traction of the vehicle, the track being elastomeric and mounted around a plurality of wheels to move about the wheels, the track comprising a ground-engaging outer surface, an inner surface opposite to the ground-engaging outer surface, and a sensor, the apparatus comprising:
