BLUESENSORS – Photonic
Technologies for Ocean
Monitoring and Exploitation

BLUESENSORS research line aims to develop innovative sensors based in photonic technology for operation in marine like environments and to address several scientific challenges that must be overcome to establish sensors operation in such harsh environments.

To address these scientific challenges INESC TEC will explore the potential of photonic based technologies, in the context of specific marine related applications investigated by CIIMAR.

Several scientific and technological aspects of sensor technology will be addressed in the context of specific applications in Aquaculture, Marine environment and sea based Biotechnology.

Each of these applications requires the combined use of different sensor technologies having associated different sets of expertise and skills.

WP1 – Physical sensors and Imaging

  • Strategies for underwater imaging using structured illumination and compressive sensing techniques, enabling self-corrected 3D image reconstruction in very compact systems will be explored in the context of biomass estimation for on-shore and off-shore Aquaculture.
  • Development of Biosampler device with incorporation of high resolution imaging systems.
  • Establishment of new multiaxial fibre sensors for physical parameters (curvature, strain, high temperature) using fs based fibre micromachining, and compatible techniques for long range (200 km) interrogation in multiple points.

WP 2 – Chemical sensors

  • Development of novel chemical optrodes comprising innovative nanostructured polymer sensing layers and robust low cost optoelectronics.
  • Incorporation and validation of chemical sensors (dCO2 ) in newly developed model tanks of hyperintensive aquaculture (Shallow raceway systems with recirculation)

WP3 – Biosensors

  • Development of novel optofluidic platforms for label-free biosensing using 3D non-linear photolithography.
  • Selection of novel bio-recognition elements based in Nuclear receptors from marine organisms, and new functional layers, for biosensors targeting environmental and pharmaceutical biotechnology applications.
  • Validation of genomic based species identification using an optimized optical biosensor platform for monitoring hybridization processes.
