Dear Narasimha,

 In our Technical university at Hamburg, Germany,
research is oriented towards using HMDSN based plasma
polymer layer as the humidity sensing polymer. As I am
not involved in this work I can not go into details.

For more details on this work have a look on the
website

http://www.tu-harburg.de/mst/english/forschung/feuch.shtml

I would advise you to search for some papers on
humidity sensing in IEEE SENSORS journals.


regards,
Venkat
Hamburg University of Technology, Germany.
