The use of sensor networks has increased in many different
settings, including industrial. The need to power the sensors all these
networks can be very troublesome, especially if the manufacturing plant
does not have the appropriate wiring installed. The less communication
and power cables to route and/or trip over, the better. If the need
to change the batteries was also eliminated, better still.
In this technical paper, Cymbet talks
about how their energy harvesting transducers can help build a zero
power wireless network.
