Patent ID: 8162534

Claim:
A ground-contacting component of a vehicle, comprising polymeric compounds, wherein at least one wireless temperature measurement system based on surface acoustic wave or bulk acoustic wave technology is embedded in a region of a polymeric compound of the polymeric compounds, the region of the polymeric compound at least one of reaching temperatures above 100° C. and influenced by a surrounding region of a polymeric compound reaching temperatures above 100° C. during use of the vehicle, and wherein the at least one wireless temperature measurement system comprises at least two wireless temperature measurement systems based on surface acoustic wave or bulk acoustic wave technology, the at least two wireless temperature measurement systems comprising linearly polarized antennas and being embedded in regions of two polymeric compounds, the regions of the two polymeric compounds at least one of reaching temperatures above 100° C. and influenced by regions of surrounding polymeric compounds reaching temperatures above 100° C. during use of the vehicle, and an angle between 30° and 90° is between the polarization directions of the antennas.
