*Abstract

Power consumption is a very important part of remote sensing and sensing networks. This is especially true when these sensors are buried in a construction material such as concrete. In particular, this disclosure is in the area of concrete and asphalt roads and road surfaces where sensors are embedded in the concrete to report various factors determined by the specific function of the sensors.These sensors are frequently connected as mesh networks such as ZigBee such that data are passed from one sensor to another until the edge of the network is reached where the particular network element at that point can communicate the air using wireless communication.The fact that the sensors are embedded makes it essentially (practically) impossible to replace batteries and difficult to power passive sensors through the concrete. Thus, if the sensors are turned on and left in that condition, the battery life is greatly compromised through the periods of inactivity when there is no traffic and no convenient means of measuring structural integrity. The appearance of a vehicle on the road provides stimulus for the sensor.
