Patent number: 9804233Abstract: The disclosure provides a magnetic field sensor for sensing the magnetic field caused by a current to be measured, which includes: substrate; a first drive electrode with a path for flowing a reference current supplied from the substrate arranged so as to be moveable by the magnetic field of the current to be measured; and a second drive electrode with a path for flowing a reference current supplied from the substrate arranged so as to be moveable by the magnetic field of the current to be measured, thus measuring the variation of a capacitance caused by the movement of the first drive electrode and the second drive electrode. Hence, the sensing is achieved by the two drive electrodes with no reference electrode, thus maximizing the mechanical displacement to improve the sensing capability.Type: GrantFiled: April 24, 2014Date of Patent: October 31, 2017Assignee: LG INNOTEK CO., LTD.Inventors: Sang Won Seo, Yong Jun Ko, Seung Hwa Kwon, Jeong Gi Seo, Chil Young Ji, Wan Seop Choi
