Touch detection device with touch interface made of composite material

The touch detection device includes a touch interface 1 made of a lignocellulosic material and a composite material containing a resin， the lignocellulosic material is impregnated with a resin， and the resin fraction is from 30% by weight to the total weight of the composite material. 80% by weight. The impregnated resin can make the touch interface stable regardless of temperature and humidity conditions for use both outside and inside. A touch detection device is used for the touch screen. A touch detection device comprises a touch interface (1) made of composite material comprising a lignocellulosic material and a resin， the lignocellulosic material being impregnated with the resin， the fraction of resin being between 30% and 80% by weight relative to the total weight of composite material. The resin impregnated makes it possible to render the touch interface stable irrespective of the temperature and moisture conditions with a view to use both outside and inside. Use of the touch detection device for a touchscreen.
