Development of innovative aldehyde sensors

"Formaldehyde Sensor Based on Carbon Nanotube"

・Sick building syndrome caused by formaldehyde is problem in many countries
・Low cost and small sensor for detection of trace formaldehyde is demanded
・Detect-to-warn sensor provide opportunities to avoid exposure to toxic chemicals,leading to improve public health

・Formaldehyde is detected as a variation of electric resistance by using CNT and chemical reaction
・Limit of detection is 0.016 ppm (WHO standard = 0.08 ppm)
・Toxic chemical can be detected by smartphone using RFID technology
