In a video I published in 2022 (), a specific method to detect pressure is shown. This method involves moving the ferrite core which then alters the resonant frequency of the LC circuit. This design is from a very, very old EMR pen design.
Modern designs use a separate pressure sensor which is more reliable for detecting pressure.
This pressure detection mechanism is discussed in great detail here:
The OLD EMR pen design can be seen in .
