Flexible touch sensor techniques are described. A touch sensitive device includes a printed circuit board (PCB) having a touch controller and a flexible printed circuit having a flexible substrate and touch sensors formed thereon using a plurality of flexible traces arranged to detect proximity of an object. The plurality of flexible traces are extended along the flexible substrate to directly terminate onto a connector of the printed circuit board thereby forming a communicative coupling between the touch sensors and the touch controller, which thereby permits the touch controller to determine a location of the proximity of the object in relation to the touch sensors.
