Abstract
In one embodiment, a touch sensor includes a first electrode and a second electrode. At least a portion of the second electrode is interdigitated with the first electrode. The first electrode includes a base portion, a digit and an extent. The digit includes a first end and a second end, connects to the base portion at the first end, and extends from the base portion in a first direction along a first axis. The extent connects to the digit at the second end and extends from the digit along a second axis that is substantially perpendicular to the first axis.
Claims20
A touch sensor comprising:
- a first electrode that comprises:
- a first base portion;
- a second base portion that comprises a first end and a second end, connects to the first base portion at the first end, and extends substantially perpendicularly from the first base portion;
- a third base portion that connects to the second end of the second base portion and extends substantially perpendicularly from the second base portion;
- a first digit that comprises a first end and a second end, connects to the first base portion at the first end, and extends from the first base portion in a first direction along a first axis;
- a first extent that connects to the first digit at the second end of the first digit and extends from the first digit along a second axis that is substantially perpendicular to the first axis;
- a second digit that comprises a first end and a second end, connects to the third base portion at the first end, extends from the third base portion, and is substantially parallel to the first axis;
- and
- a second extent that connects to the second digit at the second end of the second digit, extends from the second digit, and is substantially parallel to the second axis;
- a second electrode that comprises:
- a base portion;
- and
- a digit that comprises a first end and a second end, connects to the base portion of the second electrode at the first end, and extends substantially perpendicularly from the base portion of the second electrode, the digit of the second electrode being at least partially interdigitated with the first digit of the first electrode and the second base portion of the first electrode;
- and
- a third electrode that comprises:
- a base portion;
- and
- a digit that comprises a first end and a second end, connects to the base portion of the third electrode at the first end, and extends substantially perpendicularly from the base portion of the third electrode, the digit of the third electrode being at least partially interdigitated with the second digit of the first electrode and the second base portion of the first electrode.
