New Processing Techniques for Thin Films

Green Chemical Synthesis of Piezoelectric Thin Films 

Lead Researcher: Stuart Burns, Mohsen Mahmoudvand

Through the conversion of electrical to mechanical energy and vice-versa, piezoelectrics are key functional energy materials for next-generation sensors, actuators and ultrasonic devices. The current industry standards of piezoelectrics, however, are lead-based compositions. Given strict environmental policy over the past few decades, there is a recognized need for micro-electromechanical systems (MEMS) made from non-toxic elements and processes.

Our research aim is to establish a new green method for synthesising potassium sodium niobate (K_0.5Na_0.5NbO₃) thin films with properties that compete with current industry piezoelectrics.
