Abstract
In one embodiment, a device includes a stylus tip capable of communicating wirelessly with another device through a touch sensor of the other device. The stylus tip includes one or more surface areas, one or more substrates disposed along one or more of the surface areas of the stylus tip, and a plurality of electrodes disposed on or in the one or more substrates.
Claims20
A device comprising:
- a stylus tip of a stylus operable to communicate wirelessly with another device through a touch sensor of the other device, the stylus tip comprising one or more surface areas;
- one or more substrates disposed along one or more of the surface areas of the stylus tip;
- and
- a plurality of electrodes disposed on or in one or more of the substrates,
- wherein a first electrode and a second electrode of the plurality of electrodes are configured to transmit signals to the other device through the touch sensor and to receive signals transmitted by the other device through the touch sensor, and
- wherein the first electrode corresponds to a first vertical segment of the one or more substrates and the second electrode corresponds to a second vertical segment of the one or more substrates, wherein the first vertical segment and the second vertical segment extend along a central vertical axis of the stylus tip and are disposed adjacent to each other along a radial circumference of the stylus tip.
