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3305A1是一款超小型加速度传感器/振动传感器，自带电量放大器，集成陶瓷应变片和超低噪的电子元器件。
The Dytran 3305A1 is a lightweight miniature IEPE accelerometer offered with a sensitivity of 10 mV/g. The accelerometer incorporates a ceramic shear sensing element and ultra low noise JFET electronics, with materials housed in a highly durable 0.32-inch (8.1-millimeter) tall laser welded titanium housing weighing just 3.7 grams. The model 3305A1 features an adhesive mount and industry standard 10-32 radial connector.
