Prof. Cheng-Sao Chen received his Ph.D. degree in Mechanical Engineering from National Taiwan University of Science and Technology (NTUST) in 2007. He is now an Associate Professor in Hwa Hsia University of Technology (HHUT). His main research interest includes synthesis, crystal growth and characterization for lead-free intelligent materials including ferroelectric/ piezoelectric bismuth sodium titanate-based and silver niobate-based ceramics as well as multiferroic bismuth ferrite-based ceramics. He has used a range of characterization techniques to investigate the evolution of structures, and the correlations of material property and microstructure in these intelligent materials. 

WORKING EXPERIENCE : Director of Department of Mechanical Engineering, Hwa Hsia University of Technology, Taiwan (2017,08-2019,07). 

Academic Exchange Group and International Cooperation Group Leader in Research and Development Office, Hwa Hsia University of Technology, Taiwan (2007,10-2008,09).  

Associate Professor in Department of Mechanical Engineering, Hwa Hsia University of Technology, Taiwan (2014,02-currently).

My laboratory focuses on the functional materials.  My team develops mainly dielectric capacitors with a fast charge-discharge time, high power density, fatigue resistance, and thermal stability, which can be developed as some applications such as hybrid electric vehicles, pacemaker, integrated circuit, Iaser weapon, electromagnetic gun, ion accelerator, plasma technology.  We combine perovskite ferroelectric materials (BiFe03, Bi0.5Na0.5TiO3, BaTi03, AgNb03, NaNb03, etc.) and glass-ceramic systems to produce relaxor ferroelectric / antiferroelectric dielectric capacitors with optimized energy storage properties.  The purpose of combining the perovskite relaxor ferroelectric / antiferroelectric ceramics and glass-ceramic systems is to develop high entropy configuration that offers attractive features identified to be phase-stabilization, sluggish diffusion, and local Iattice mismatch and distortion.  The optimized compositions will be utilized for the process approach in fabricating the multilayer ceramic capacitors (MLCCs) via tape casting technique in order to maximize the superior energy storage performance in dielectric ceramics for actual industrial applications.  The approach will focus in designing integrated MLCC devices with large Wrec, high and Eb, fast charging-discharging time, excellent fatigue- and thermal-stability.
