The proximity sensor feature in my PSOC4 is working exactly like I need for my application.  However,  I'd like to find a way to shield a portion of the "antenna" so that it doesn't respond to proximity.  

I can explain further if needs be.  

Also, I'll try to keep checking the post, since (and I keep having this beef with the forum) the forum doesn't email notify.

You might post a CASE on this -

By sheilding one would think you lower the delta C allowed for detection,

eg. you are adding shield C to the static load on the key. However I wonder

if you bootstrapped the shield with an OpAmp if that would work. I have never

tried it, not a CapSense expert, but just thinking.....(which as my wife points out

often is a miracle for me when it happens)


Regards, Dana.
