How do the measurement function of ADXL345 with the differential capacitors work?

Hi,

 

in my lectures I would like to explain the students an accelerator sensor. I would like to use your ADXL345. In the data sheet, there is a small section saying that the acceleration measure function is based on the differential capacitor method. To explain it to the students, it would be great if I could have more information about the implemenation an placing oft the capacitors. Maybe have you got some pictures, sketches, application notes or equations?

 

Best regards
