Abstract
The SAW configuration type
interdigital transducers configuration
fabrication technology and process
as well as the sensitive material and coating methods
are studied in detail.Using poly epichlorohydrin(PECH)as the sensitive coating for mustard gas(HD)
a novel dual-path SAW resonator gas sensor is designed and tested.The results show that such sensor has merits of good stability
high sensitivity
fast response
suitability for the continunous and real time detection
which is an ideal gas sensor for chemical warfare agents detection.
