Single-wire sensor/actuator network for structural health monitoring
First Claim
1. A structural health monitoring system, comprising:
- a plurality of sensors configured to be spatially distributed along a structure and to transmit electrical signals upon detecting stress waves within the structure; and
wherein each sensor of the plurality of sensors is placed in electrical communication with each other sensor of the plurality of sensors.

Abstract
A sensor/actuator network configured with a number of electrically-interconnected elements. More specifically, the sensors/actuators are each placed in electrical communication with the same transmission line. Various embodiments of such networks employ sensors/actuators connected in electrical series and in electrical parallel. Networks having these configurations, when placed upon a structure, are capable of detecting and/or transmitting stress waves within the structure so as to detect the presence of an impact, or actively query the structure. Advantageously, as these networks employ a single transmission line, they utilize fewer wires than current sensor/actuator networks, thus making them easier to install and maintain. They can also be configured as flexible layers, allowing for further ease of installation and maintenance.
