本文概述了MEMS传感器在汽车和消费电子中的关键应用,如汽车稳定控制、硬盘保护和安全气囊触发。它展示了MEMS如何使电子控制系统更智能、精确和快速,超越人类反应能力。
A car is skidding, and stabilizes itself without driver intervention; a laptop falls to the floor, and protects the hard drive by parking the read/write drive head automatically before impact; an airbag fires before the driver/occupant involved in an impending automotive crash impacts the steering wheel, thereby significantly reducing physical injury: – all systems involved are based exclusively on MEMS sensors. These crucial MEMS-sensor components of electronic control systems are making system reaction to human needs more intelligent, precise, and at much faster rates than humanly possible. Important prerequisites for the success of sensors are their size, functionality, power consumption, and costs. Such technical progress in sensor development is realized by micro-machining. The development of these processes was the breakthrough leading to industrial mass-production of Micro ElectroMechanical Systems (MEMS). Besides leading-edge micromechanical
