1. A track for traction of a vehicle, the track being mountable around a track-engaging assembly configured to move the track around the track-engaging assembly, the track-engaging assembly comprising a plurality of wheels for engaging the track, the track being elastomeric to flex around the track-engaging assembly, the track comprising:
a ground-engaging outer surface for engaging the ground;
an inner surface opposite to the ground-engaging outer surface;
elastomeric material;
a monitoring device configured to issue a signal, the monitoring device comprising an electronic component carried by an electronic component substrate, and a piezoelectric generator configured to power the monitoring device, wherein the piezoelectric generator has a piezoelectric element deformable in response to deformation of a portion of the elastomeric material of the track to generate power, wherein the piezoelectric generator has an electrical conductor electrically interconnecting the piezoelectric element and the electronic component; and
a protective substance coated on at least a portion of the electronic component of the monitoring device and allowing the signal to pass through the protective substance and the elastomeric material of the track, wherein the protective substance is inside the elastomeric material and engages the electronic component, the electrical conductor, and the piezoelectric generator, wherein the protective substance encapsulates the electronic component substrate, and wherein a portion of the piezoelectric generator extends from the protective substance and is uncovered by the protective substance.
