When a customer with high level quadriplegic ordered a Stylus Socks II, two custom approaches were taken for a proper experience. Under normal circumstances, the energy of the finger flows to the iPad's touchscreen when holding the stylus' conductive fabric. But when using the mouth, this is no longer the case.
In approach 1, a regular conductive fabric Stylus Sock is wrapped around an aluminum stick. When taking the stick in the mouth, you get a conductive chain that transports the human body's energy to the screen.
In approach 2, a regular Stylus Sock with a pen holder is used. An extra slice of conductive fabric connects the sock with the body of the iPad. This piece of fabric transports the iPad body's energy to the screen. As such, any regular mouthstick can be used; just wrap a Stylus Sock around the tip and connect it with a slice of the same conductive fabric to the iPad's body. So now it's the iPad instead of the human body that generates the required energy. Credits go to friend and out-of-the-box thinker Bart van der Weijden who came up with this solution!
Both approaches don't require a wire in the mouth. And of course a mix is possible of both approaches.
