1. A flexible capacitive touch sensing device, comprising:
a first sensing region and a second sensing region, each of the first sensing region and the second sensing region comprising:
flexible material; and
a plurality of electrodes, disposed in or on the flexible material, wherein the electrodes of the first sensing region and the second sensing region are electrically connected via conductive material or conductive components; and
a capacitance detection circuit, configured to sense capacitance caused by the electrodes, wherein the capacitance is used for detecting if an object causes capacitance variation to at least one of the first sensing region and the second sensing region;
wherein the first sensing region comprises a first side region with a first side, and the second sensing region comprises a second side region, wherein the first side is adjacent to the second side;
wherein the electrodes of the first side region and the second side region are overlapped in normal directions of the first side region and the second side region;
wherein an angle which is not 0° exists between the electrodes which are overlapped.
