3D Printing a piezoelectric sensor in one go!

Before she finished her PhD and left the Laboratory for Multiscale Mechanics at Polytechnique Montréal, Sampada Bodkhe invented a way to 3D print piezoelectric sensors in one step: she coextrudes the active sensor and the electrodes together in one go, without the need for a subsequent poling or treatment step. Just print your sensor and its ready to use!
You can read a popularized account of her work on Advanced Science News. FYI, we applied for a patent with Gestion Univalor.

Single Step 3D Printing of Piezoelectric Sensors

New publication on the reconfiguration of rods

Trees bend and twist when subjected to wind. This deformation, or reconfiguration, allows the tree to reduce its drag. In our paper published in the Journal of Fluids and Structures we investigate how torsional and bending deformations play different roles in reconfiguration. We investigate this through a combination of wind tunnel experiments on flexible reinforced foam rods and a theoretical Kirchhoff rod model.
