Compact Photonic Fibre-based Deformation Sensor Fabricated by Two-Photon Polymerization

We have demonstrated that compact deformation sensors with heights and widths of about 100 micrometers can be fabricated by two-photon polymerization, using commercially available optical ferrules with embedded 125 micrometers-diameter optical fibers as the basic platform and the commercial photopolymers OrmoComp and FemtoBond as the fabrication materials.
