  • Capacitive sensor and manufacturing method of capacitive sensor
    Patent number: 11662328
    Abstract: A capacitive sensor includes a sensing electrode, a first electrode pad, a substrate, and a second electrode pad. The sensing electrode outputs a signal corresponding to a capacitance between the sensing electrode and a detection target. The first electrode pad is coupled to the sensing electrode. The substrate includes a substrate surface portion and a step portion. On the substrate surface portion are the sensing electrode and the first electrode pad mounted. The step portion is provided at a position in the substrate lower than the substrate surface portion. The second electrode pad is mounted on the step portion and coupled to an external line.

  • Capacitance detection area sensor and conductive pattern sensing apparatus having capacitance detection area sensor
    Patent number: 11567114
    Abstract: A capacitance detection area sensor includes capacitance sensor elements arranged in a two-dimensional array, is shaped into an appropriate shape, and capacitively coupled to an external electrode. To the external electrode, a sensing signal having a potential difference is supplied. The first and second sensor output signals are acquired from a capacitance sensor element capacitively coupled to the external electrode, at the timing of the sensing signal being a first signal and being a second signal, respectively. A differential signal is generated from a difference between the acquired first and second sensor output signals, and an image indicating the shape of the external electrode is generated based on the level of the differential signal, in different colors or different tones.
