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3032A是一款微型IEPE加速度传感器/振动传感器，灵敏度10mV/g，重量仅1.5g。
The Dytran 3032A is a lightweight, miniature IEPE accelerometer, weighing just 1.5 grams and an overall footprint height of just 0.28 inches (7.1 millimeters).
Available with a sensitivity of 10 mV/g, the model 3032A incorporates a quartz sensing element, operating in shear mode, housed in a lightweight titanium construction. Units feature adhesive mounting and an 18-inch integral coaxial cable terminating to a 10-32 jack.
