Advances in Electronics: A Pilot Study on Tissue Deformation in Aquaculture

Strategic Insights

— 1 min read

Researchers from the University of South-Eastern Norway have conducted a pilot study to evaluate the feasibility of using sensor-actuator systems for minimally invasive procedures in aquaculture. The study, published in a recent issue of Electronics, involved developing a sensor-actuator setup to measure tissue deformation in Atlantic Salmon during needle insertion. The results indicate minimal biomechanical disruption, suggesting the potential for ethical and automated sampling techniques in aquaculture and livestock applications.

Key Takeaways:

  • The pilot study integrated three types of low-cost, commercially available force sensors to capture force profiles and identify biomechanical events associated with tissue layer transitions.
  • Controlled insertions were performed on a deceased specimen, and the resulting force data were analyzed to quantify insertion dynamics and estimate tissue deformation, which ranged from 0.001 μm to 8.4 μm and from 0.3 N/m² to 4.9 N/m², respectively.
  • A simulation model based on the recorded force values was developed to calculate stress distribution and deformation, supporting the feasibility of using sensor-actuator systems for minimally invasive procedures.
  • The results indicate minimal biomechanical disruption, with implications for fish welfare and potential applications in aquaculture and livestock.
  • The study lays the basis for future research involving live specimens and blood sampling.
  • The integrated sensor-actuator setup offers a pathway toward automated sampling techniques.
  • The University of South-Eastern Norway's research team, led by Ishrak Siddiquee, collaborated with Md Ebne Al Ashad and Ahmed Hasnain Jalal to conduct the study.

Statistics:

  • The study measured tissue deformation in Atlantic Salmon during needle insertion, with values ranging from 0.001 μm to 8.4 μm.
  • The calculated stress distribution and deformation values ranged from 0.3 N/m² to 4.9 N/m².
  • The findings have important implications for fish welfare, offering a pathway toward ethical and automated sampling techniques in aquaculture and livestock applications.
  • The study involves future research involving live specimens and blood sampling to further develop and validate the sensor-actuator system.
