    Abstract: A multitouch-capable touchscreen is realized in that a large number of pressure sensors are attached under a flexible surface and thus both the pressure distribution and also the deformation of the surface is measured. Local pressure maxima occur due to the flexibility of the surface material with associated deformation on contact. As several local pressure maxima can exist, it is thus also possible to identify a plurality of contacts simultaneously. It is possible from the strength of pressure and pressure distribution to determine the force that is used for pressing such that this information can also be used in the user interface. Such sensors can be produced very efficiently and inexpensively by printing an ink that changes its resistance under pressure onto PCB tracks designed as sensor surfaces. The PCB tracks and the sensor surfaces can also be printed out using an ink with as low a resistance as possible.

    Abstract translation: 实现了具有多触点功能的触摸屏，其中大量的压力传感器附着在柔性表面下，因此测量了表面的压力分布和变形。 局部压力最大值是由于表面材料的柔性而导致触点相关变形。 由于存在若干局部压力最大值，因此也可以同时识别多个触点。 从压力和压力分布的强度可以确定用于按压的力，使得该信息也可以在用户界面中使用。 这样的传感器可以通过印刷在压力下将其电阻改变为设计为传感器表面的PCB轨迹的油墨而非常有效和廉价地制造。 PCB轨迹和传感器表面也可以使用尽可能低的电阻的墨水打印出来。
