What is the core structural element that printed electronics are designed to sense the physical change in when medication is dispensed?

Answer

Deformation caused by pushing out a tablet

The embedded sensors and antennas, created using printed electronics applied directly to the blister card substrate, possess a specific functional requirement. They are engineered not just to detect proximity or general movement, but specifically to sense the physical deformation that occurs when the patient executes the standard action of pushing a tablet out of its protective pocket. This mechanical stress or change in the substrate integrity is what triggers the electronic capability to register that the medication has been dispensed. This mechanism ensures that the digital record corresponds directly to the physical act of removal.
