Sensor pattern for a tactile input device

摘要

A tactile sensor includes a plurality of first sensing elements that are arranged in a plurality of rows on a first layer and a plurality of second sensing elements that are vertically aligned in a plurality of columns on the first layer. The second sensing elements in each column are electrically connected together and each of the plurality of columns are separate conductors from one another. The plurality of second sensing elements include a plurality of vertical elements that form an interlocking pattern with the plurality of first sensing elements.
