Summary:Summary form only given. An untapped opportunity in the realm of
wireless data lies in low data-rate (<10 kb/s) low-cost wireless
transceivers, assembled into distributed networks of sensor and actuator
nodes. This enables applications such as smart buildings and highways,
environment monitoring, user interfaces, entertainment, factory
automation, and robotics While the aggregate system processes large
amounts of data, individual nodes participate in a small fraction only
(typical data rates <1 kb/s). These ubiquitous networks require that
the individual nodes are tiny, easily integratable into the environment,
and have negligible cost. The challenges and opportunities in the design
of integrated wireless sensor and actuator nodes, to be used in such
self-configuring ad-hoc networks, are described. To be viable, the node
must be smaller than a couple of mm3, cost <$1, and
consume <100 μW, allowing for energy scavenging from the
environment
