MUMBAI, India, July 31 -- Intellectual Property India has published a patent application (202647088204 A) filed by Alps Alpine Co. , Ltd. on July 20, 2026, for Electrostatic Input Device And Electrostatic Detection Device.
Inventor includes Fujiki, Takashi.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: Provided are: an electrostatic input device with which the accuracy of determination in failure determination can be improved by reducing an output sensitivity of electrostatic capacitance when performing failure determination on a sensor electrode; and an electrostatic detection device. The electrostatic input device comprises: a sensor electrode provided on a back side of an operation surface; a measurement circuit connected to the sensor electrode; a determination unit that, on the basis of an electrostatic capacitance of the sensor electrode obtained from an output of the measurement circuit, performs failure determination for determining the failure of the sensor electrode, and that performs an operation determination for determining the contact or the approach of an object with respect to the operation surface; and a sensitivity setting unit that sets a first output sensitivity of the measurement circuit when the determination unit is performing the failure determination to be lower than a second output sensitivity of the measurement circuit when the determination unit is performing the operation determination.
