Abstract
A structure which detects the application point, intensity and area of the force and the pressure applied, along with the touch, and the forces applied in vertical direction to the sensor as well as the combined forces, which has reduced power consumption. The sensing system has an intermediate layer; a light source located under the intermediate layer; an image sensor located under the intermediate layer; a first fiber optic bundle; a second fiber optic bundle; a control unit which analyzes the image captured by the image sensor using image processing techniques; and a data link for data communication between the image sensor and the control unit.
Claims12
A sensing system (S) that detects touch, comprising:
- at least an intermediate layer (1);
- at least an upper layer (4) located on the intermediate layer (1);
- at least one light source (2) located under the intermediate layer (1);
- at least one image sensor (3) located under the intermediate layer (1);
- at least a first fiber optic bundle (5a) which comprises a plurality of fiber optic cables positioned such that a tips of which is facing to the light source (2) and other tips of which is facing to the said intermediate layer (1), and which transmits the light obtained from the light source (2) to the upper layer (4) located on the intermediate layer (1);
- at least a second fiber optic bundle (5b) which comprises a plurality of fiber optic cables, a tips of which is paired with at least one pixel of the image sensor (3) and other tips of which is positioned facing to the said intermediate layer (1), and which transmits the image of the upper layer (4) located on the intermediate layer (1) to the image sensor (3);
- at least one control unit which analyzes the image captured by the image sensor (3) using image processing techniques so as to calculate a force applied on the intermediate layer (1);
- and
- at least a data link (6) for data communication between the image sensor (3) and the control unit
- characterized in that the said upper layer (4) comprises a polarized film or a piezochromic material as a material that changes color with force.
