◆Background◆
・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
◆Aim◆
・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
