Journal ArticleDOI
Transparent and flexible piezoelectric sensor for detecting human movement with a boron nitride nanosheet (BNNS)
Kyung Bum Kim,Wooree Jang,Wooree Jang,Jae Yong Cho,Sang Bum Woo,Deok Hwan Jeon,Jung Hwan Ahn,Seong Do Hong,Hye Young Koo,Tae Hyun Sung +9 more
TL;DR: In this article, a transparent and biocompatible boron nitride nanosheet (BNNS) material with a TFPS device is proposed for wearable electronics, which is able to generate electrical energy from mechanical push force and human movement.
Journal ArticleDOI
Optimized composite piezoelectric energy harvesting floor tile for smart home energy management
Kyung-Bum Kim,Jae Yong Cho,Hamid Jabbar,Jung Hwan Ahn,Seong Do Hong,Sang Bum Woo,Tae Hyun Sung +6 more
TL;DR: A floor tile is presented which can be used at different locations in the home and can generate enough energy to wirelessly transmit the information to electrical appliance when a person steps on it, and is utilized to power a wireless sensor node which can control the power on and off function of home appliances in a real-time.
Journal ArticleDOI

Gyeong Ju Song,Kyung Bum Kim,Jae Yong Cho,Min Sik Woo,Jung Hwan Ahn,Jong Hyuk Eom,Sung Min Ko,Chan Ho Yang,Seong Do Hong,Se Yeong Jeong,Wonseop Hwang,Sang Bum Woo,Jeong Pil Jhun,Deok Hwan Jeon,Tae Hyun Sung +14 more
TL;DR: In this paper, a speed bump piezoelectric harvester (SBPH) was used to charge mobile phones using a self-controlled battery charging system via electricity generated by the pieziolectric module.
Journal ArticleDOI
A multifunctional road-compatible piezoelectric energy harvester for autonomous driver-assist LED indicators with a self-monitoring system
Jae Yong Cho,Kyung Bum Kim,Wonseop Hwang,Chan Ho Yang,Jung Hwan Ahn,Seong Do Hong,Deok Hwan Jeon,Gyeong Ju Song,Chul Hee Ryu,Sang Bum Woo,Jihoon Kim,Tae Hee Lee,Ji-Young Choi,Haimoon Cheong,Tae Hyun Sung +14 more
TL;DR: It was found that the z-axial loaded piezoelectric devices with a two-end fixed beam provide high output power with low levels of vertical displacement, making it highly efficient and durable for actual highway energy-harvesting applications.
Journal ArticleDOI
A High Efficient Piezoelectric Windmill using Magnetic Force for Low Wind Speed in Wireless Sensor Networks
Chan Ho Yang,Yewon Song,Jeongpil Jhun,Wonseop Hwang,Seong Do Hong,Sang Bum Woo,Tae Hyun Sung,Sinwoo Jeong,Hong Hee Yoo +8 more
TL;DR: A piezoelectric windmill optimized at low-speed wind is designed to gather wind energy and the output power and the efficiency of the system were compared with a conventional wind power system.
