A Comparative Study of BaTiO3/PDMS Composite Film and a PVDF Nanofiber Mat for Application to Flexible Pressure Sensors
Donghyuck Park, Kwanlae Kim
Korean J. Met. Mater. 2021;59(6):412-421.   Published online 2021 May 26
DOI: https://doi.org/10.3365/KJMM.2021.59.6.412

Abstract
Intensive research has been conducted to develop flexible piezoelectric pressure sensors, since selfpowering devices are advantageous for wearable electronic applications. Recently, two types of piezoelectric devices, ceramic-PDMS composite film and PVDF nanofiber mats, have drawn attention in the research community. Piezoelectric ceramics such as BaTiO3 (BTO) and PZT exhibit outstanding..... More

Evaluation of the Mechanical Properties of ZnO Nanorods Treated with Oxygen Plasma using Atomic Force Microscopy
Donghyuck Park, Yijun Yang, Kwanlae Kim
Korean J. Met. Mater. 2021;59(3):209-216.   Published online 2021 Feb 19
DOI: https://doi.org/10.3365/KJMM.2021.59.3.209

Abstract
Zinc oxide (ZnO) simultaneously exhibits semiconducting and piezoelectric properties. ZnO in the form of nanorods has been studied intensively for application in self-powering devices. The power generation in piezoelectric nanogenerators based on ZnO nanorods can be improved via several approaches, including an oxygen plasma treatment. When ZnO nanorods are exposed..... More
