Abstract: A conductive brush, or stylus, for use with touch screen computing devices. The bristles or filaments are attached to an electrically conductive ferrule, so that even when the brush is pressed against the tablet to make the bristles splay apart, the conductive ferrule itself maintains electrical communication with the tablet.

This deformation at least partially absorbs stresses on the filaments, preventing them from splaying apart excessively during painting, and thus helping to prevent loss of detection by the tablet and/or undesired visual effects.
