Abstract
An apparatus includes a force sensor circuit and a controller. The force sensor circuit includes first, second, third, and fourth electrodes disposed on a substrate. The first and second electrodes extend through first and second cells of a row of cells. The third and fourth electrodes extend through third and fourth cells of a column of cells. The first electrode occupies more area in the first cell than in the second cell. The second electrode occupies more area in the second cell than in the first cell. The third electrode occupies more area in the third cell than in the fourth cell. The fourth electrode occupies more area in the fourth cell than in the third cell. The controller detects a force and a position of the force based on signals communicated by the force sensor circuit.
