Fibers are materials that have a very long length compared to their cross
sectional dimensions, i.e. a very high aspect ratio.
A wide variety of everyday objects are either made out of or consist of
fibers (clothes, wall paper, chairs). In this work, we describe a potential
physical layer for wearable computing by using fibers. The layer is
defined by the fabrication of transistors onto fibers, packaging and
these packaged fibers into textiles. These fibers need be made out of
suitable semiconductor materials to host transistors. A piece of
polysilicon produced into a very small cross section compared to its
length is demonstrated. Due to space constraints on a single fiber,
research into novel architectures is done to create parallel,
distributed, fault-tolerant and configurable devices. Configurable
fibers can be interwoven into clothes or everyday objects to create
artifacts, which can be interconnected with each other.
