Extension sensing of piezo actuators using time-domain ultrasonic measurement and frequency-domain impedance measurement
TL;DR: In this article, three different techniques of extension sensing for multilayer piezoelectric actuators, to provide a suitable method which involves primarily overcoming the inherent hysteretic behaviour of PAs materials.
