Fiber photodetectors codrawn from conducting, semiconducting and insulating materials

assembly of such fibers into two-dimensional (2D) grids, or photodetector fiber webs, which enables the detection of an illumination point. Moreover, this grid achieves N 2 detection resolution with only a 2N number of elements. Figure 1(d) shows an example of a fiber web detector being used to measure the coordinates of an illumination point on a 30 30 cm2 grid with 64-point resolution. We expect that such metal, insulator and semiconductor flexible fibers will pave the way for the future development of fibers, and even fabrics, with novel optical and electrical properties.
