  • wire - How to use a capacitive touch screen without a

    Actually, capacitive touch screens do not require to be touched by a body that can source current, rather, they sense when contacted by any conductor (see wikipedia article on capacitive sensing). Since wire is a prototypical conductor, you do not need to touch it to use it as a makeshift stylus.

  • What material can I lay over a capacitive touch screen

    The capacitors on a capacitive touch screen appear as a series of very thin (so thin you can see through them) metal contacts on the non-touched side of the screen. The change in capacitance developed by your finger in proximity to these is what it senses, so as long as the material is thin enough to not interfere with this, it should be fine.

  • Introduction to Capacitive Touch Sensing - Technical Articles

    Capacitive touch sensors fall into two general egories: the mutual-capacitance configuration and the self-capacitance configuration. The former, in which the sensing capacitor is composed of two terminals that function as emitting and receiving electrodes, is preferred for touch-sensitive displays.

  • How Capacitive Touchscreen Works - EN-TOUCH

    Some of the advantages of capacitive touchscreen technology include: Durability — one of the greatest benefits of capacitive touchscreen is its strength and durability.
