The drive and two sense electrodes are arranged on the bottom side of a dielectric panel, the top side providing a sensing surface to be touched by a user's finger or a stylus. The additional sense electrode is positioned on the underside of the dielectric panel so that it is shielded from the drive electrode by the conventional sense electrode. The signal collected from the additional sense electrode is subtracted from the signal collected from the conventional sense electrode to cancel noise."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive sensor with additional noise-registering electrode","description":"A capacitive touch sensor employing adjacent drive and sense electrodes, in which an additional sense electrode is provided as well as a conventional drive electrode and sense electrode.
