New developments in sensor technology have resulted in sensors for smart tire systems that are more precise, dependable, and reasonably priced. The capabilities of smart tire systems are increased by new sensor technologies that allow for exact measurement of tire pressure, temperature, tread wear, and other performance indicators. These technologies include MEMS (Micro-Electro-Mechanical Systems) sensors, capacitive sensors, and optical sensors.
For instance, in September 2023, Infineon Technologies AG introduced the XENSIV SP49 tire pressure monitoring sensor. The new feature in the product enables it to provide intelligent tire functions with integrated hardware support. Moreover, the sensor is also compatible with on-tire auto-position sensing. The embedded interval timer in the SP49 devices produces a wake-up, and the devices are appropriate for low-power stand-alone remote pressure sensing applications.
