These milestones demonstrate the proven reliability of CMC products in demanding automotive-grade environments and the high level of trust from the global market.
Driving the Next Generation of Intelligent Vehicle Sensing
As a technology leader in the automotive sensing field, CMC continues to drive innovation as its core growth engine while deepening and expanding its presence in the automotive market. The launch of the CAAP02B not only proves CMC’s strong R&D capabilities in MEMS technology, but also represents a significant milestone in the evolution of automotive sensing solutions. As demand for vehicle intelligence continues to accelerate, CMC remains committed to providing automakers and end users with more precise and reliable sensing solutions that effectively enhance driving safety and overall vehicle performance.
Coretronic MEMS Launches World’s Smallest TPMS Accelerometer, Expanding Presence in Automotive OE Market
Coretronic MEMS Corporation (CMC), a subsidiary of Coretronic Corporation (5371.TW), officially announced the launch of CAAP02B on December 15, the world’s smallest three-axis analog accelerometer designed specifically for Tire Pressure Monitoring Systems (TPMS). This innovation represents a major breakthrough in micro-electro-mechanical systems (MEMS) processing technology, offering exceptional shock resistance and high reliability for automotive applications, and providing global automakers with a lighter, more efficient, and safer solution for tire pressure monitoring.
Automotive-Grade Reliability in the Tiniest Sensor
The CAAP02B three-axis accelerometer is purpose-built for TPMS applications. With an ultra-compact size of 0.89mm × 0.83mm, it is currently the smallest solution in its class worldwide. Unlike standard consumer-grade sensors, the CAAP02B leverages CMC’s proprietary piezoresistive sensing technology and is manufactured on a dedicated automotive-grade process platform developed in collaboration with leading wafer foundries. This technology effectively mitigates stiction issues commonly encountered in high-G environments, significantly enhancing long-term product reliability.
