Overview
Recently, fabric area network, or wearable network has been investigated to form a body sensor network (BSN) for healthcare or multimedia applications. Wearable network has 4 unique networking situations:
First, since clothes are multilayered, such as underwear, inner wear, and outer wear, low power wireless links to couple the multilayered clothes are necessary. Second, 2-D network structure is embedded in 3-D clothes space, and its 3-D clothes shape changes over time and with gesture (dynamic deformation). Third, knitting and weaving are not electrically exact technologies, and their properties are too irregular and inefficient for communication (static parameter variation). Finally, clothes in nature are prone to tearing and wearing out, so the network must be fault-tolerant.
In this project, a low energy inductive coupling link with a low energy fault-tolerant wearable body sensor network (BSN) controller is proposed to realize intra- and cross-layer wearable network at once. And the design considerations of woven inductor with conductive fabric wires are introduced.
