Abstract
An inductive touch sensor comprises an inductors disposed in or on a deformable substrate. When a force is applied to the deformable substrate the physical shape of the inductor will change and thereby change its inductance value. The change in the inductance value can be detected and used to indicate actuation of an associated touch key of the inductive touch sensor. A plurality of inductive touch sensors may be used to form a touch panel.
