IEPE是指一种自带电量放大器或电压放大器的加速度传感器。IEPE是压电集成电路的缩写。因为由加速度传感器产生的电量是很小的，因此传感器产生的电信号很容易受到噪声干扰，需要用灵敏的电子器件对其进行放大和信号调理。IEPE中集成了灵敏的电子器件使其尽量靠近传感器以保证更好的抗噪声性并更容易封装。
美国Dytran的3035B是一款微型IEPE加速度传感器/振动传感器，灵敏度100mV/g，自带电量放大功能。
The Dytran 3035B is a miniature IEPE accelerometer, available with a 100 mV/g sensitivity, an overall height of just 0.33 inches (8.3 millimeters) and a total weight of 2.5 grams.
Sensors feature a rugged stainless steel construction, 5-40 stud mount and 5-44 radial connector. Units are hermetically sealed for reliable operation in high humidity and dirty environments.
