Expert Answer:

The changing factor could be mechanical such as distance between the plates or area of place surface which overlaps in a capacitor with many semicircular plates, fixed to a rotating axis.

Some semiconductor capcacitors are electronical made variable capacitors by changing the thickness of depletion layer and doping.
