Wireless sensor network technology is being widely studied and applied today. The introduction of Berkeley-Mote technology has provided researchers from many disciplines with a novel research tool. This talk will review the development and application of "Mote-like" technology from the CRIM at NC State University. First, deployments of environmental sensor networks have focused on obtaining measurements across large and inhospitable areas. However, scale and the prospect of randomly distributed networks often lead to areas without connectivity. This quickly becomes an issue. The talk will examine how a low cost and adaptive method of robotic repair can be applied to large area networks using received signal strength measurements for simple navigation and placement. Second, the talk will look at the development and use of modular wireless sensor nodes for wearable health monitoring, using system on textile techniques. Even with the current limitations associated with the fabrication and production of wearable computing systems, the talk will describe wireless sensor nodes that can monitor and report on ECG, respiration, and/or rehabilitation and athlete performance metrics. Lastly, the talk will show how "Mote-like" technology can be applied for the health monitoring of engineered structures.
