ABSTRACT:
A monitoring assembly for a pneumatic tire includes an electronic monitoring device having at least one sensor disposed in a protective body. The protective body includes an encapsulation layer that encapsulates the substrate and sensors, a cushion, and a skin on the outside of the cushion. The protective body is substantially spherical allowing the assembly to roll about the inside of a tire without being permanently connected to the tire. A breathing tube through the protective body is provided so that a pressure sensor can sense the pressure within the pneumatic tire. The breathing tube may be filled with a transfer gel to prevent the breathing tube from being clogged. The monitoring assembly may further include wings that help position the monitoring assembly within the tire. The antenna of the monitoring device may be disposed within one of the wings. The monitoring assembly is simply placed in a tire before the tire is mounted on a vehicle rim and allowed to move about loosely in the tire chamber when the tire is in use.
