Using Electrospinning for the Fabrication of Rapid Response Gas Sensors Based on Conducting Polymer Nanowires 2008-06-15 01:15:00 Early detection of trace amounts of toxic gases in an open environment is vital for any successful attempt to contain subsequent damage. The sensors used must respond quickly and reliably in such a situation. A typical method to increase sensitivity is to use sensors that have a large exposed area. It is also desirable for the sensor to be small in size and to consume low power. These characterist Read more:Rapid
