With the advantages of small size, high precision, good stability and strong adaptability, miniature weighing sensors have become the core components in the field of precision weighing and force detection, and are widely used in many industries such as industrial automation, intelligent equipment, light industrial manufacturing, scientific research and medical treatment, etc., providing important support for intelligent equipment and precise detection.

As the "nerve endings" to perceive the physical world, the force sensor is reconstructing the underlying logic of vehicle performance and safety with micron-scale accuracy. From the engine room to the intelligent cockpit, from the production workshop to the monitoring of driving conditions, the force sensor becomes the core support of the whole life cycle of automobile manufacturing, testing and operation by converting mechanical stress into quantifiable electrical signals. This paper systematically sorts out the types of force sensors commonly used in the automobile industry:
