Abstract
The capacitive detector of position between two supports (10 and 30) comprises a series of electrodes (11) on support (10) and a series of electrodes (13) on support (30). The electrodes (13) of support (30) and electronic circuitry (21) are formed on the lower face of an integrated circuit substrate (20) constituting the electronic part intended for the application of incremental potentials to the electrodes (13).
