I swear I did a search and did not come up with anything substantial. I just want an understanding how the tire pressure sensor internally works. Does it detect the amount of force being applied upon it? Basically how does it sense the pressure? The reason I am asking is I took the sensor out when I was changing my rear tire and wanted to change the battery. I got a new battery, but it is a PITA to solder a wire to the battery. So what I did is shown in the picture. It appears they fit fine, but wanted to put a rubber grommet on top and bottom to make sure enough pressure gets applied to the disc to make contact. If I do put rubber grommets, the encasing becomes tougher to shut. So was thinking perhaps I can press it in and just put tape around it (or secure it in some other means). But did not want that to cause issues with functionality.
I've put this together for your enjoyment....actually for anyone else interested in these sensors and their issues.

Still working on it but am at least up to page 25 in rooting out the TPMS threads. You're right in that it's damnably difficult to search these out as we all use different terms. It ain't no better on the 'other' site either using search.
Went to Batteries Plus.......they spot welded tabs on and soldered them in place.....cost 6 bucks and I gave the tech a '$10 tip for doing the WHOLE thing for me. Heat can destroy both the battery and the circuit board and the spot welder does the job well. Just take them in separate bags so you don't confuse the front and the rear sensors.
