压电式加速度传感器，又称振动传感器，是基于压电晶体的压电效应工作的。某些晶体在一定方向上受力变形时，其内部会产生极化现象，同时在它的两个表面上产生符号相反的电荷；当外力去除后，又重新恢复到不带电状态，这种现象称为“压电效应”，具有“压电效应”的晶体称为压电晶体。常用的压电晶体有石英、压电陶瓷等，在现代生产生活中被应用于许许多多的方面，如手提电脑的硬盘抗摔保护，目前用的数码相机和摄像机里，也有加速度传感器，用来检测拍摄时候的手部的振动，并根据这些振动，自动调节相机的聚焦。压电加速度传感器还应用于汽车安全气囊、防抱死系统、牵引控制系统等安全性能方面。
美国Dytran的3010M14是一款微型加速度传感器/振动传感器，专为传输标准振动标定数据，对其他加速度传感器进行标定，例如3120B和3123A型。
The Dytran 3010M14 is a primary transfer standard accelerometer, and is designed to transfer standard vibration calibration data from standards organization such as NIST, to back-to-back calibration accelerometers such as Dytran models 3120B and 3123A, which are then used to calibrate other accelerometers.
Back-to-back (reference) accelerometers offer a convenient means of determining the sensitivty and frequency response characteristics of unknown acceleration, velocity and displacement sensors. A vibration laboratory already equipped with an electrodynamic shaker and control system can easily incorporate use of the model 3010M14 to accomplish in-house NIST traceable calibrations, Model 3010M14 is available with a 10 mV/g sensitivity, 10-32 tapped hole for mounting, and 10-32 axial connector.
