Have you ever thought of the situation that why the screen video mode of your cellphone would change from vertical mode to horizontal mode automatically when your phone slopes to one side? Why the controller of a game machine will response changes of the direction, speed and acceleration? These user-friendly functions are backed up by the accelerating sensors in the MEMS. It is the sensors that are the key factors, and also are the reason why intelligent phones have become so popular.

MEMS is also called Micro-Electro-Mechanical Systems which has many applications in the modern technologies. Made by micro fabrication technology, the MEMS the a technology which integrates sensors, machinery components, actuators and electronic components on a public silicon chip. MEMS is often seen as a kind of system of chip, making the development of intelligent products become a reality. It also has got the access to many secondary markets and has provided solutions to industries including auto, cellphone, biological technology and health care. Besides, MEMS is used in bulk acoustic awave duplexers, filters, microphones and pressure sensors.

At present, the MEMS main products are the pressure sensors and the accelerometers. However, the original microphones using this technology are becoming popular. Omron sensor technology is used to improve the tone quality and has excellent reliability which will create good cost efficiency for the new video frequency. Furthermore, this kind of microphone is much smaller even than the smallest electrets condenser type and is insensible to temperature change, mechanical vibration and electromagnetic interference.

It is obvious that MEMS has found its way in applications of our daily life. Low cost and small volume are the two main engines for its popularity, therefore, smaller, lighter and cheaper products can be made. However, challenges also exist in the package problem. Costs will be doubled easily because of variety of components and the various environment in which each product is produced. The main target for engineers is to find a kind of much cheaper package. Today, with the fast progress in projects, there will be a much newer understanding of the technology. Related chip is:HA11221 .
