A customer currently has a ceramic board manufactured off shore and he is
looking to redesign it and have it made "locally".  It is a ceramic board
which has an aluminum oxide coating on one side.  This coating must be very
thin and highly resistant to abrasion as well as being non-conductive. 
Contacts under the coating are wiped with a sensor.  

He is looking for an alternative to the ceramic/aluminum oxide combination.
 Can anyone help?

Regards
