The technology that these 3 kinds of sensor place use basically has 3 kinds: Pressure block, press report and capacitance technology, every kinds of technology has respective opportunity and problem. As a result of the wide application in auto industry development of sensor of acceleration of the type that control block is the rapiddest, acceleration sensor basically is used at automobile safety gasbag, prevent hold dead system, drawing in the arms to command the safety performance respect such as the system. As a result of security more and more become car manufacturer sell a site, this kind of additional system is increasing also. The market dimensions 2000 is sensor of acceleration of the type that control block about 420 million dollar, the basis concerns investigation, predict its market prise will be pressed year average 4.1% rate rise, come to reached 560 million dollar 2007. This among them, the rate of European market is the rapiddest, because Europe is the seat of a lot of safe gasbag and car production company. The technology that suppress report basically is used on industry avoid machine error, use this kind of sensor to be able to detect the trouble with potential machine is protected oneself with achieving, reach avoid to produce accident harm to the worker, this kind of sensor has an user, especially the user place of quality industry goes after but repeatability, stability and autogenous sex. But in a lot of new application fields, a lot of users still do not have the consciousness that uses this kind of sensor, the market that distributors takes a risk to enter this kind to still await development will be troubled great, because terminal user is right,know as a result of the issue that use this kind of sensor and brings and means of settlement not much. If these problems can get settlement, will promote the sensor that suppress report to get rapidder development.
