710535Bay Systems Limited: Proof of Concept of a wireless sensor to measure Tyre Cavity TemperaturesClosedGRD Proof of ConceptInnovate UKBay Systems Limited are developing a proof of concept of a wireless Tyre Cavity Temperature sensor which can be easily fitted, is small enough to fit inside the tyre and robust enough to work whilst the tyre rotates. Accurate internal temperature measurements will improve tyre design accuracy since direct measurements within the tyre cavity will not be reliant on modelling assumptions. The proof of concept requires the design of sensor and electronics, packaging and measurement approaches to enable reliable operation in the very constrained space available between tyre and rim. These sensors need to be compact, wireless and able to withstand the large forces and unavoidable rough handling as tyres are fitted, removed and driven in test conditions. Creating this sensor is important to tyre and vehicle manufacturers who need to understand the complex tyre material behaviours in real world conditions. This requires accurate measurements of physical tyre parameters such as temperature inside the tyre as it rotates under realistic conditions, whether in the lab or on the road. A robust, reusable sensor that is easy to use will enable this internal measurement to be cost effectively included in the tyre development regime. Improving the design of vehicle tyres can make a critical contribution to improving vehicle ride quality, durability, energy consumption, noise and particulate matter emissions.
