本文主要是石英晶体微天平（QCM）的原理简介，该设备能够监测电极上的微小质量变化。

The QCM-I and QCM-I Mini systems are designed to be modular so that they can be configured to use the sensors and fluidics that are most appropriate for the user’s experiments.

This Application Note is intended to provide the reader with a general framework for characterization of an electroactive polymer film.
