the SHiMmer project

SHiMmer is a wireless platform that combines active sensing and localized processing with energy harvesting to provide long-lived structural health monitoring. SHiMmer uses piezoelectric transducers (PZTs) to evaluate a portion of a structure to determine if damage exists. Unlike other sensor networks that periodically monitor a structure and route information to a base station, our device acquires data and processes it locally before communicating with an external device, such as a remote controlled helicopter.

The overall objective for the SHiMmer project is to create a working, dependable, robust structural health monitoring platform. Within this larger objective, there are many smaller ones including: (1) fabricate a working platform capable of being powered using solar cells, (2) create a robust and flexible software controller that can manage both the energy and the task execution, (3) combine this controller with complex SHM algorithms to provide meaningful results, (4) test this device in the field, and (5) create a method for communication and collaboration between multiple nodes (a SHiMmer network.)
