Yes (usually temperature drift is a bigger issue), generally there is some (moderately complex) low pass filter that maintains a relatively stable baseline and recovers gracefully (no false positive, minimal false negative) from noise/moisture/thermal and other adverse events.

One interesting case is buttons in your pocket or face down on a desk. This is made more complex when low power requirements are made (e.g. lower sampling rate). A second is breathing on a very cold device. There are guarding methods that reduce the effect of moisture, but they may also run into IP challenges.
