    • Pulse wave velocity measurement with soft-polymer optical fibers for wearable continuous blood pressure monitoring 

      Stefani, Alessio; Rukhlenko, Ivan; Ward, Rebecca; Prinable, Joseph; Large, Maryanne; Fleming, Simon
      Published 2020
      Soft-polymer fibers allow strong conformal contact with the skin and are extremely sensitive for deformation, despite high propagation loss. This enables pulse wave velocities measurements. Blood pressure can then be ...

    • OAM generation, tunable metamaterials and sensors with highly deformable fibers 

      Stefani, Alessio; Lwin, Richard; Kuhlmey, Boris; Fleming, Simon
      Published 2018
      A flexible fiber-drawn material, i.e. polyurethane, allows for novel applications from THz to the visible. We exploit its elastic properties to generate orbital angular momentum modes, to make pressure sensors and to ...
