Suspended gate field effect transistor modified with polypyrrole as alcohol sensor
Abstract
A generic type of new type of solid state gas sensor is described which uses change of electron work function of a chemically sensitive layer in response to interaction with a gas or vapor. It is shown that if this layer is electrochemically deposited polypyrrole the device responds to lower aliphatic alcohols. The new sensor operates at room temperature and has time response in seconds.
