Would alumide work for a capacitive touchscreen stylus?

    I'm thinking it might because a capacitive stylus doesn't need to be continuously conductive: it just needs enough conductive material in it to cause a distortion of the screen's electrostatic field.

    If nobody has tried it, could somebody please? Take a chunk of alumide with a flat surface of at least the size of a flattened fingertip and see if a phone or tablet screen reacts to it.

    Hi,

    Alumide is not electrically conductive, and when asked, my son said 'You aren't getting that stuff anywhere near my iPod screen, it'll scratch it to buggery'.

    An alternative us to use the packing foam used for silicon chips etc which is conductive. There are plenty of videos on YouTube showing how this can be ustilised.

    Is polished alumide still scratchy?

    I've no polished Alumide yet, however I just tried some polished WSF on a thick sheet of polythene, no scratching at all after a minute of heavy rubbing.
