The research team of Professor Ha Tae-Jun (Department of Electronic Materials Engineering) has successfully developed a wearable high-sensitivity capacitive humidity sensor by synthesizing hydrophilic polyvinylpyrrolidone (PVP) and combining it with multi-walled carbon nanotube (MWCNT)-based flexible electrodes. The results of this research were published in Sensors and Actuators B: Chemical (IF: 8.4, JIF ranking: 99.2%), a top international journal in the field of chemical sensors published, , by Elsevier, under the title 'All-printed wearable humidity sensor with hydrophilic polyvinylpyrrolidone film for mobile respiration monitoring.'
