From STM32 (https://www.st.com/content/ccc/resource/technical/document/application_note/9d/be/03/8c/5d/8c/49/50/DM00088471.pdf/files/DM00088471.pdf/jcr:content/translations/en.DM00088471.pdf):
The Cs capacitance is a key parameter for sensitivity. For touchkey sensors, the Cs value is usually comprised between 8.7nF to 22nF. For linear and rotary touch sensors, the value is usually comprised between 47nF and 100nF. These values are given as reference for an electrode fitting a human finger tip size across a few millimeters dielectric panel.
