PRINTED FORCE SENSOR WITHIN A TOUCH SCREEN |
摘要 |
A quantum tunneling composite, or other material exhibiting changing electrical or magnetic properties as force on the material is increased, can be located within a force concentrator integrated into traditional touch screen layers to sense force applied on the touch screen. The force concentrator can be a protrusion from the layer planes of the layers in a traditional touch screen and can be formed, at least in part, from printed elements. The amount of protrusion of the force concentrator can be adjusted through multi-pass printing and thicker deposit printing. The force concentrator can also have optically clear adhesive layered over it. The force-sensitive material can be optionally pre-loaded so as to operate within a substantially linear feedback range. A sensing mechanism can be configured to detect changes in force at multiple locations or to detect the application of force irrespective of location. |
