Touch sensing system, multi sensor device and vehicle control device

A multi sensor device, comprising:

• a frame work;
• a first sensor layer, surrounding the frame work;
• a second sensor layer, surrounding the first sensor layer;
• a flexible material layer, located between the first sensor layer and the second sensor layer, and surrounding the first sensor layer;
• and
• a flattening material layer, located between the second sensor layer and the flexible material layer or located between the first sensor layer and the flexible material layer, wherein the flattening material layer flattens the flexible material layer;
• wherein the second sensor layer is above the flexible material layer when the first sensor layer is below the flexible material layer;
• wherein the first sensor layer has at least one first driving electrode and at least one first sensing electrode;
• wherein the second sensor layer comprises at least one second driving electrode and at least one second sensing electrode.

A vehicle control device, comprising:

• a frame work;
• a heating layer, surrounding the frame work;
• a first layer, surrounding the heating layer;
• a flexible material layer, located between the heating layer and the first layer, and surrounding the heating layer;
• and
• a flattening material layer, located between the first layer and flexible material layer or between the heating layer and the flexible material layer, wherein the flattening material layer fills at least one aperture or at least one crack of the flexible material layer;
• wherein the first layer is above the flexible material layer when the heating layer is below the flexible material layer;
• wherein the first layer comprises at least one first electrode;
• wherein the heating layer has at least one heating electrode.
