Abstract
Disclosed is a sensor for monitoring a composite structure. The sensor includes multiple sensing elements of different sizes, each configured for different respective monitoring tasks. Also disclosed are methods of fabricating the sensor, designing and manufacturing the sensor, and attaching the sensor to the composite structure.
Claims16
A sensor for monitoring a composite structure, the sensor comprising:
- a first sensor element configured to detect data associated with a first monitoring task, the first sensor element including a first positive electrode having a first size;
- and
- a second sensor element configured to detect data associated with a second monitoring task, the second sensor element including a second positive electrode having a second size,
- wherein the first positive electrode and the second positive electrode are coupled to an active sensing element at respective bottom surfaces via a first conductive layer configured to conduct electricity in only a vertical axis, the active sensing element configured to produce an electric current when placed under mechanical stress and having a size larger than a combination of the first size and the second size.

A sensor for monitoring a composite cylinder configured to store a fluid, the sensor comprising:
- a first sensor element having a first size and configured to detect data associated with a first monitoring task;
- and
- a second sensor element having a second size and configured to detect data associated with a second monitoring task,
- wherein the first monitoring task is detecting a direct wave energy from an object when the composite cylinder endures impact damage from the object, and
- wherein the second monitoring task is detecting damage to the composite cylinder as the composite cylinder is filled with the fluid.
