MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202617057531 A) filed by Sumida Corporation on May 06, 2026, for Sensor Device.
Inventors include Miyazaki, Hiroyuki; and Hatakeyama, Takeshi.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: A sensor device (1) comprises: a magnetic material core part (2) capable of forming a closed magnetic circuit including two outer leg parts; two coil parts (L1 and L2) that are respectively formed by winding wires around the two outer leg parts and each generate a signal magnetic flux according to an alternating-current signal applied; a magnetic flux generation unit that generates a bias magnetic flux so that the bias magnetic flux circulates through the closed magnetic circuit; an alternating-current signal circuit (3) for applying an alternating-current signal to each of the two coil parts so that a signal magnetic flux in the same direction as the bias magnetic flux is generated in each of the outer leg parts; and signal output terminals (V1 and V2) for outputting detection signals that allow for detection of voltage balance between the two coil parts (L1 and L2) that changes according to an external magnetic field acting on the magnetic material core part (2).
