1. A distributed monitoring system for monitoring one or more operating conditions of a structure, comprising:
- one or more sensor nodes coupled to the structure, each sensor node comprising;
a power supply adapted to scavenge energy directed at the power supply;
a sensor operably coupled to the power supply for sensing one or more operating conditions of the structure in the immediate environment; and
a communications interface operably coupled to the power supply and the sensor for communicating the sensed operating conditions of the structure; and
one or more readers positioned proximate the sensor nodes, each reader comprising a transceiver adapted to communicate with the sensor nodes;
wherein the readers are adapted to acquire data from the sensor nodes representative of the operating conditions either intermittently or continuously.

17. A method of operating a system for monitoring one or more operating conditions of a structure, comprising:
-
providing sensor nodes at locations around the structure for sensing operating conditions of the structure; positioning the structure proximate another structure; directing radiated energy from the other structure at one or more of the sensor nodes; scavenging the radiated energy at one or more of the sensor nodes; and using the scavenged energy at one or more of the sensor nodes to transmit sensed operating conditions from one or more of the sensor nodes to one or more readers either intermittently or continuously. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
