Capacitive control interface device and method adapted for the implementation of highly resistive measurement electrodes

摘要: The present invention relates to an interface device for controlling actions of at least one object interest, comprising (i) a detection surface (4) provided with plurality capacitive‑measurement electrodes (5), (ii) electronic and processing means excitation able polarize said measurement (5) alternating electrical potential, measure capacitive coupling between electrode (iii) guard elements (6) made electrically conducting material which are polarized potential substantially identical (iv) linking tracks (7) disposed in part on (4), the arranged such way as generate frequency low enough coupled capacitively interest their track have impedance whose resistive is much lower than modulus reactive part. also apparatus method implemented this or apparatus.
