Local mechanical properties of perovskite oxide ferroelectric materials
Ferroelectric materials have the ability to convert electrical energy into mechanical energy and vice versa, which makes them widely used as sensors, actuators, and ultrasonic transducers. While their electrical and electromechanical properties are well studied, mechanical properties like Young’s modulus (E) and hardness (H) remain known to a lesser extent. …
Pneumatic variable stiffness mechanisms for application in lower-limb exoskeletons
Wearable robotics holds promise for enhancing human capabilities and addressing motor challenges in individuals with impairments, amputations, or those who are healthy. Exoskeletons, among various wearable devices, are designed to be worn on the upper or lower limbs. While some applications, like in the medical field, have been widely adopted, …
Study of polar ordering in ordered and partial disordered ferroelectric systems
This work presents experimental studies of ordering phenomena, electromechanical and electrocaloric properties in single crystal, ceramic and solid solution relaxor ferroelectrics and single crystal ferroelectric materials. The main aim of investigations is to prove the existence of a liquid-vapor critical point in these systems and to verify its impact on …
