Proposal of a new mechanism for research on piezoelectric generators using human body motion\
Jeonbuk National University postdoctoral researcher Sam-yeon Cho (Department of Physics, College of Natural Sciences, Supervisor Professor Sang-don Sang) recently won the ‘Yangsong Researcher Award’, the highest award at the 2022 Spring Conference of the Korean Ceramic Society.
The Korea Ceramic Society is one of the three major academic societies representing the domestic materials field, and is an academic conference for the communication and sharing of knowledge on the development of the domestic materials and parts industry. About 800 research papers were presented at this conference, including general sessions and special symposiums, small research group workshops, and ACERS Korea Chapter Symposium.
The Yangsong Researcher Award, awarded by Researcher Sam-yeon Cho, is one of the “Yangsong Awards” awarded to the society development fund donated by Nam Nam-dong Yang, who served as president of the Ceramic Society, etc. One of the top prizes for postdoctoral researchers who have achieved outstanding research results in ceramics.
At this conference, Dr. Sam-Yeon Cho presented the research result of ‘Manufacturing a wearable energy harvester using the gigantic deformation behavior of BNT-based relaxed ferroelectric ceramics’ and received favorable reviews.
This study relates to a wearable piezoelectric generator using a phase transition induced by external tensile force, structural deformation and induced polarization in an ergodic relaxed ferroelectric material, which has not been generally used as a material in the field of piezoelectric generators due to its relatively low piezoelectric coefficient.
The published study proposed a new driving mechanism for the study of piezoelectric generators using human motion in the field of energy harvesting, which has recently received much attention, and is evaluated as a study that can greatly contribute to improving the performance of wearable piezoelectric generators.
