Abstract
An electrode for an input device can be designed to reduce wobble over a range of input device orientations. The electrode can include a spherical portion and a tapered portion. In some examples, the electrode can linearly taper away from the spherical portion. In other examples, the electrode can non-linearly taper away forming an elliptical flare. Additionally or alternatively, the electrode can include a spring-loaded member that can couple the electrode to other circuitry of the input device. Additionally or alternatively, the electrode can include a neck portion coupled to the tapered portion, and part of the neck portion can be shielded. The input device can include a first non-conductive material disposed on part of the spherical portion of the electrode and a second non-conductive material disposed between part of the electrode and the first non-conductive material.
