What makes a touchscreen work?
When an object, such as a fingertip or stylus tip, presses down onto the outer surface, the two layers touch to become connected at that point. The panel then behaves as a pair of voltage dividers, one axis at a time. By rapidly switching between each layer, the position of pressure on the screen can be detected.
Why does touchscreen only work with finger?
In other words, they look for changes in a uniform electrical charge that’s applied to the top layer. When a capacitive touchscreen is turned on, an electrical charge will be applied to its top layer. Upon touching the top layer with a bare finger, your body will absorb some of the electrical charge.
Why do bananas work on touch screens?
The glass of your touchscreen actually sits above dozens of small electric fields in a grid formation — and when your finger glides across the screen, it triggers a change in those electric fields. … That’s why bananas can also swipe right — they conduct electricity about as well as your finger.
Is a touch screen a sensor?
A touchscreen “sensor” is a clear glass panel with a touch responsive surface. This sensor is placed over an LCD so that the touch area of the panel covers the viewable area of the video screen.

What can I use instead of my finger on a touch screen?
In addition to copper, aluminum is another material that works with capacitive touchscreens. While aluminum isn’t as conductive as copper, it’s still able to conduct electricity — just like your bare fingers. As a result, it’s supported by capacitive touchscreens.
What is the best type of touch screen?
The advantages of Surface Capacitive touch technology is that it offers users a better image quality than 5-wire resistive touch. The screen tends to be more durable and boasts excellent water, grease and dust resistance, as well as a high resistance to scratching.
