Efficacy of tooth brushing via a three-dimensional motion tracking system for dental plaque control in school children: a randomized controlled clinical trial
Autor: Jin-Sun Jeong, Kyeong-Seop Kim, Jeong-Whan Lee, Kee-Deog Kim, Wonse Park
Publikováno v: BMC Oral Health, Vol 22, Iss 1, Pp 1-8 (2022)
Abstract Background School children are in a developmental period in which permanent teeth replace primary dentition. It is also a period with a high incidence of gingivitis and caries, which can be improved with adequate tooth brushing. Advances in

Wearable Fabric Loop Sensor Based on Magnetic-Field-Induced Conductivity for Simultaneous Detection of Cardiac Activity and Respiration Signals
Autor: Hyun-Seung Cho, Jin-Hee Yang, Sang-Yeob Lee, Jeong-Whan Lee, Joo-Hyeon Lee
Publikováno v: Sensors, Vol 22, Iss 24, p 9884 (2022)
In this study, a noncontact fabric loop sensor based on magnetic-field-induced conductivity, which can simultaneously detect cardiac activity and respiration signals, was developed and the effects of the sensor’s shape and measurement position on t

Development of a Chest-Belt-Type Biosignal-Monitoring Wearable Platform System
Autor: Jin-Hee Yang, Je-Wook Chae, Sang-Min Kim, Joo Hyeon Lee, Hwi-Kuen Kwak, Jeong-Whan Lee, Hyunseung Cho
Publikováno v: Journal of Electrical Engineering & Technology. 15:1847-1855
The purpose of this study was to develop a wearable platform system that can detect and acquire a soldier’s biosignals (i.e., heart activity signal, respiration rate, etc.) in a nonrestrained, unconscious manner. These detected biosignals are trans

Sensing efficiency of three-dimensional textile sensors with an open-and-close structure for respiration rate detection
Autor: Hyunseung Cho, Jin-Hee Yang, Soo-hyun Oh, Hyeok-Jae Lee, Hwy-Kuen Kwak, Joo Hyeon Lee, Jeong-Whan Lee, Je-Wook Chae
Publikováno v: Textile Research Journal. 90:2258-2274
The strain-gauge type textile sensors adopted in many studies on respiration-sensing wearable systems have been reported to have two major limitations that result in reduced sensing accuracy and insufficient durability of the sensor. The two limitati

Pre-processing of Photoplethysmographic Waveform for Amplitude Regularization
Autor: Hangsik Shin, Jeong-Whan Lee, Jae-Pil Kim
Publikováno v: Journal of Electrical Engineering & Technology. 14:1741-1748
This study is aimed to develop a post-processing method to regularize amplitude of PPG waveforms and evaluate the performance of the algorithm. The proposed procedure for regularizing amplitude consists of extracting the signal envelopes based on tim
