Developing techniques to measure piezoelectric coefficients in 3D
As the piezoelectric properties are a function of the form of the printed structure, it is essential to study them in their 3D format. The goal of this thesis is to develop a technique to obtain the piezoelectric coefficients of 3D structures.
Keywords: 3D printing, electromechanical, characterization, sensors, actuators
Three-dimensional (3D) piezoelectric materials come with the advantages of leveraging the coupling of different piezoelectric coefficients to achieve a higher electro-mechanical conversion leading to higher power output in energy harvesters. 3D printing of piezoelectric materials is thus essential in creating customized and integrated piezoelectric sensors for aerospace, sports, biomedical and automobile applications. Although several techniques have been successful in creating 3D piezoelectric materials, characterization of these 3D printed structures is still a major concern.
