Abstract
The analysis, modeling, and validation of a piezoelectric energy harvester utilizing a radioisotope source are presented and discussed. The device employs tritiated silicon as a radioisotope source to drive the charging and actuating cycles of the piezoelectric cantilever. Tritiated silicon emits energetic β particles which lead to charge partition, creating an electrostatic force between the tritiated substrate and the piezoelectric cantilever. Due to this continuous charge–discharge procedure, vibrational cycles are generated in the piezoelectric cantilever. The energy from the piezoelectric capacitor is appropriately rectified to provide electrical power to a microelectromechanical system (MEMS) device. The modeling results have been analyzed and compared with the available experimental results, showing a very good agreement. Thus, the analytical and modeling study can be applied to optimize piezoelectric energy harvester designs.

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
