‘Electronic Nose’ To Detect Toxins
Professor Nosang Myung at Bourns College of Engineering, University of California, Riverside (UCR), has developed a prototype “electronic nose” designed to detect harmful airborne agents such as pesticides, gas leaks, biological weapons, and other unwanted substances. UCR has exclusively licensed the tech to Nano Engineered Applications to fabricate a working prototype, shrinking it from the present 4×7 inches (10×18 cm) to the size of a credit card. The device is to hold a computer chip, USB ports, temperature and humidity sensors, a Bluetooth to sync with smartphones, and a GPS receiver, with Wi-Fi being considered too. The sensor originates from a nano-sensor array utilizing carbon nanotubes 100,000 times finer than human hair to spot airborne toxins down to the parts per billion level Myung has been developing for eight years.
