Touch operation made easier.

Touch operation is made possible by Algra Group's innovative strain gauge technology, Dynaforce, which turns rigid surfaces into an input front in the blink of an eye.

Strain gauge technology detects even the slightest deformation

Whether on your smartphone, at public machines or around the house - for many people, touch-based operation has become a firmly established part of everyday life. The Algra Group's strain gauge technology makes touch operation possible on more atypical surfaces such as metal, wood or even ceramics.

"The strain gauge technology recognises even the smallest deformations in the material layer," explains Dieter Matter, CEO of the Algra Group. "This is enough to activate the button and trigger a function." This technological feat is made possible by intelligent software and a sensor network that is made up of strain gauges. These can determine where you are touching and thus activate the button.

Freely combinable options
The Dynaforce sensors are extremely touch-sensitive and function without problems on sheet thicknesses of between 0.3 and 1.2 mm. There is one of these sensors for each button on the circuit board. This network of sensors then detects even the finest mechanical deformations and uses the intelligent software to filter out interfering signals.

As these sensors are force sensors, functions can be differentiated based on the force exerted upon the sensor. With a lamp, for example, a hard press of the button may cause the light to turn on, while a gentler press of the button could lower the brightness.

Another possibility is visual feedback through an LED or a display. In addition, you can choose any sound to play as acoustic feedback. With Dynaforce, these variants can be combined in any way you wish.

Design that is pleasing on the eye
Typical applications are designer products that are used around the house, in an industrial setting, or in a public space, as well as applications with high demands on robustness and water resistance. The input technology will blow you away with its elegant design, its easy installation process (peel-and-stick), its operational capability in a wide range of temperatures (-40° C to +85° C), and the fact you can operate the buttons even when you are wearing gloves.
