(Phys.org) -- A UK company has developed an electronic nose that the company says can make a real difference, as a fast-acting device for detecting harmful substances in the environment. Peratech claims its electronic nose can pick up the presence of volatile organic compounds (VOCs) quickly and that its fast-acting sniffer has a large response signal (change in electric charge). The company also says its sensors have low power requirements that could be supplied by a small dedicated power source integrated into clothing.
