Abstract: Fiber pattern applicator systems and methods are provided such as for use in creating sensors. A fiber pattern applicator system comprises a fiber writer device that includes a hollow tube having a fiber channel extending therethrough from a proximal end to a distal end. A fiber input aperture is located at the proximal end of the tube, and a fiber guide tip is located at the distal end of the tube. A fiber spool is provided with a continuous fiber material wound thereon. The fiber material is threaded through the fiber channel from the input aperture through the guide tip of the fiber writer device. In a method of forming a fiber pattern on a substrate, the continuous fiber material is applied from the fiber guide tip in a predetermined pattern to a surface of the substrate. The fiber material adheres to the surface of the substrate at a position where initially applied from the guide tip.
