加速度傳感器，包括由硅膜片、上蓋、下蓋，膜片處于上蓋、下蓋之間，鍵合在一起；一維或二維納米材料、金電和引線分布在膜片上，并采用壓焊工藝引出導(dǎo)線；工業(yè)現(xiàn)場(chǎng)測(cè)振傳感器，主要是壓電式加速度傳感器。其工作原理主要利于壓電敏感元件的壓電效應(yīng)得到與振動(dòng)或者壓力成正比的電荷量或者電壓量。目前工業(yè)現(xiàn)場(chǎng)典型采用IEPE型加速度傳感器，及內(nèi)置IC電路壓電加速度傳感器，傳感器輸出與振動(dòng)量正正比的電壓信號(hào)。

4. Perform ride quality and other "whole body" human response studies"

5. Complete university engineering degree coursework and thesis papers

6. Establish the basis for a simplified machinery condition monitoring program

7. Quickly quantify and pinpoint sources of unwanted vibration

8. Measure tilt angles on heavy equipment, construction sites, and structures

9. Survey anything to get a feel for what's happening - the first step towards fixing it!
