US Patent 8981242 Inductive touch sensor and detecting method

An inductive touch sensor is provided. The inductive touch sensor comprises a driving layer for generating a magnetic field, an induced layer facing to the driving layer for identifying at least one induced electrical signal representing a change, in inductance corresponding to at least one touch location on the inductive touch sensor and at least one inductive circuit connected to the driving layer and the induced layer for detecting at least one induced electrical signal to determine at least one touch location on the inductive touch sensor. Furthermore, a detecting method of detecting at least one touch location on the inductive touch sensor is also provided.
