BANF has partnered with Silicon Labs to develop a new tire sensor system that can process data in real time without using a battery.
According to the companies, BANF has added Silicon Labs’ BG22 ultra-low-power Bluetooth Low Energy system-on-chip to its tire-embedded sensor called iSensor.
The iSensor is placed on the inner surface of a tire. It measures three-axis acceleration, air pressure, and temperature up to 4,000 times per second.
By analyzing this data, the system can detect tire tread wear, wheel misalignment, loose wheel nuts, and slippery road conditions.
Most traditional tire pressure monitoring systems (TPMS) only measure tire pressure, but BANF’s technology provides much more detailed information about tire and road conditions.
“Although tires generate vast amounts of data related to friction, load and mechanical stress, there has been no effective way to capture and transmit that data in real time,” said Yoo Sung-han, chief executive of BANF. “By combining Silicon Labs’ BG22 with BANF’s wireless power technology, we are opening a new dimension of tire intelligence.”
BANF was founded in December 2020 by Yoo. He holds a master’s degree in electrical and computer engineering from Seoul National University. Before starting the company, he worked on wireless power research and development at LG CNS.
BANF’s tire sensor iSensor won an Innovation Award at CES 2026. The technology has also been selected for pilot programs with Volvo and open innovation projects with Hyundai Motor.
In the growing smart-tire technology market, BANF faces competition from other companies. One example is Revvo Technologies, a U.S. startup founded in 2018. Revvo provides tire monitoring systems for commercial fleet operators, using sensors and artificial intelligence software. The company has raised about $23 million in total funding, including $12 million in a Series A round announced in February.
Revvo’s system sends sensor data to the cloud for analysis, but its sensors run on batteries that need to be replaced regularly.
Large tire manufacturers such as Bridgestone, Goodyear, and Continental are also working on smart-tire technologies, increasing competition in this sector.
