Simultaneous 2D Strain Sensing Using Polymer Planar Bragg Gratings

Simultaneous 2D Strain Sensing Using Polymer Planar Bragg Gratings

We demonstrate the application of polymer planar Bragg gratings for multi-axial strain sensing and particularly highlight simultaneous 2D strain measurement. A polymer planar Bragg grating (PPBG) fabricated with a single writing step in bulk polymethylmethacrylate is used for measuring both tensile...
