Claims13
A vehicle tyre comprising a piezoelectric device, characterised in that the piezoelectric device comprises
- a layer of a piezoelectric polymer having first and second opposing sides, and
- a first and a second layer of an electrically conductive rubber composition provided adjacent to the first and second opposing sides of the layer of piezoelectric polymer,
- wherein the piezoelectric polymer is selected from the group of polyvinylidene fluoride (PVDF) polymer or co-polymers and the electrically conductive rubber composition is based on a sulfur crosslinkable rubber component,
- wherein the PVDF surface is crosslinked to the electrically conductive rubber composition via a silane having thiocyante groups and ethoxy or methoxy groups, or having thiocyanate groups and ethoxy and methoxy groups.
