  • Touch sensor
    Patent number: 9740330
    Abstract: In one aspect, a touch sensor includes a dielectric surface layer; drive electrodes disposed on the dielectric surface layer and arranged radially about a center, the drive electrodes defining a perimeter about the center, and a sense electrode disposed on the dielectric surface layer and arranged between two of the drive electrodes. Each drive electrode can include: an outer radial section extending radially along the perimeter; a central section extending from the outer radial section towards the center; and an inner radial section comprising a first section extending radially away from the central section in a first radial direction and a second section, shorter than the first section, extending radially away from the central section in a second radial direction.
    Type: Grant
