A force measuring method for a touchscreen device makes it possible to measure the force applied to the touchscreen. The principle of the invention consists in measuring the displacement of the two plates supporting the conduction lines and columns of the touchscreen, a displacement which is proportional to the force applied. The displacement of the plates is known by analysis of the variation of the capacitive impedance induced by the presence of an actuator to displace the plates. |
