Abstract (en)

[origin: WO2014170180A2] The present invention concerns a method of capacitive sensing, implementing a plurality of electrodes (5, 7) capable of enabling the detection of objects (1) in the vicinity of same by capacitive coupling, and comprising a step of simultaneously polarising at least one portion of said electrodes (5, 7) with different excitation potentials, said excitation potentials being generated relative to a reference potential such that the scalar product over a predefined period of at least two of these excitation potentials is zero or much lower than the scalar product of one and/or the other of these excitation potentials with same over said predefined period. The invention also concerns a device and an apparatus implementing the method.
