Abstract
The success of ocean observation relies on effective monitoring technologies with increased functionalities, minimized size, and reduced cost. In this study, opto-microfluidic devices for sensing the salinity and temperature of sea water are proposed and demonstrated, which can be prepared with ultrafast laser fabrication and two-photon polymerization techniques. By applying femtosecond lasers as a powerful tool to achieve laser microfabrication with unprecedented high precision and quality, a Mach-Zehnder interferometer (MZI) has been fabricated and integrated into a microchannel as a miniaturized opto-microfluidic system. When the temperature changes or different saline solutions are introduced to the microchannel, different phase shifts in the MZI can be induced. The sensitivities of salinity and temperature have been found to be 215.744 nm/RIU and 0.519 nm/℃ for the opto-microfluidic systems developed in this study. Considering the impact of the temperature perturbation to the phase shift, temperature calibration is proposed for a precise salinity measurement. The results demonstrate the practicability of opto-microfluidic devices for real-time salinity and temperature monitoring of sea water in harsh environment.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
