         15 . The non-resistive contact sensor assembly of  claim 7 , wherein the inner region includes a biasing structure that acts to hold the sensor device in place, thereby minimizing the likelihood of sensor movement against the object surface and leading, in turn, to less chance of contact electrification and movement artifacts. 
     
     
         16 . The non-resistive contact sensor assembly of  claim 15 , wherein the biasing structure includes a spring. 
     
     
         17 . The non-resistive contact sensor assembly of  claim 7 , wherein the inner region includes material that is relatively triboelectrically matched to the surface of the object being measured, tested, or the like, thereby minimizing the chances that charge separation will occur when this region and the surface of the object may move together.
