Capacitive touch

A simple touch or swipe

Touch-sensitive user interfaces have seen an enormous emergence in the last decade, no doubt influenced by the popularity of tablets and smartphones that use the same principle. A mere touch or swipe of the finger on the control panel is translated into an action. This offers an intuitive user experience and makes the technology fit for a wide range of applications in every sector and domain. The translucent panels offer a nearly limitless number of possibilities for backlighting, design and branding. On this page we will tell you everything about the possibilities of capacitive touch.

“Capacitive touch sensors offer intuitive user interaction and endless design possibilities.”

Capacitive sensor technology

Capacitive sensor technology is based upon the constant monitoring of the electrical capacity of the touch area, which is changed by a human finger. As the human body is an electrical conductor, touching the surface of the screen results in a distortion of the screen’s electrostatic field. Depending on the location of the touch and the movement that is detected by the capacitive touch sensor (swiping, tapping), a specific action will be triggered.

Popularity of capacitive touch screens

Capacitive touch screens are used for a wide range of applications, from home appliances to industrial machines, and it’s still on the rise. The reason for their popularity is obvious. Not only do they offer a very intuitive and pleasant user experience, they are also very familiar to users of mobile phones, tables, tv-sets and laptops. There is also an important aesthetic aspect. The translucent capacitive touch panels offer a nearly limitless number of possibilities for backlighting, flexible sensors, custom coverlens, electronics, design and branding. Black panel effects have made the user interfaces – often a thorn in the eye of designers – almost invisible when they are not being used. 

Capacitive touch sensors: endless design possibilities

When people think of touch screens today, they typically think of flat surfaces with backlighting indicating where the keys or touchpoints are. But capacitive touch controls offer so much more. Through rapid advancements in printed electronics, they are transformed into truly smart surfaces, offering a wide range of new design and functional possibilities. There is simply no reason why a touch screen should still be flat – it can take on any shape, from curved surfaces to 3D shapes. Wireless communication technologies are easily added, creating many new functionalities.
