By combining ultra-low-power Bluetooth-based semiconductors and wireless power transmission technology, a technology has been developed that can transform the tire area, which has been difficult to digitize, into a real-time data platform, which is expected to further improve automobile safety and operational efficiency in the future.

Low-power wireless semiconductor company Silicon Labs and domestic intelligent tire system specialist BANF unveiled next-generation automotive tire monitoring technology on the 11th.

The core of the solution presented this time is the application of Silicon Labs' Bluetooth Low Energy (Bluetooth LE) SoC 'BG22' to Banff's tire-embedded sensor system.

The technology is designed for autonomous vehicles and connected platoon environments, and can detect and analyze tire conditions in real time without batteries.

Existing tire pressure monitoring systems (TPMS) only provide warnings when air pressure drops.

In contrast, Banff's intelligent tire solution measures acceleration, pressure, temperature, and wear conditions inside the tire at high speed, analyzes them instantly, and converts them into information that can be used for vehicle control.

The inside of a tire is a challenging environment for wireless communication due to metal belts and thick rubber layers.

BG22 is designed to maintain stable communication performance even under these conditions, so that you can driveIt also enables highly reliable data transmission.

Additionally, instead of sending raw data collected from sensors, only key signals are selected and transmitted, thereby minimizing communication delay and power consumption.

The power supply problem was also solved wirelessly.

Banff has implemented wireless power transfer using magnetic resonance technology through a smart profiler installed on the exterior of a vehicle.

This allows the tire's internal sensors to be continuously powered without a battery, while also enabling high-frequency data collection and processing.

It also meets automotive-grade security requirements. Silicon Labs' security technology prevents tire data tampering and external attacks, ensuring stability even in autonomous driving and large-scale vehicle operation environments.

Based on this technology, Banff plans to expand its application to various mobility sectors, including autonomous trucks, driverless buses, and logistics vehicles. In the future, the company plans to leverage accumulated tire data to expand its business into predictive maintenance, route optimization, and insurance-linked services.

An industry insider said, "This is an example of tires being transformed from mere consumables into data assets," and added, "It is evaluated as a technology that can simultaneously improve vehicle safety and operational efficiency."
