Abstract

fetched live from OpenAlex

As sources of energy are becoming more scarce and expensive, energy harvesting technologies that convert ambient energy to electrical energy are receiving more global interest. Proposed in this article are two hybrid energy harvesters that each employs a combination of piezoelectric (PZT), magnetostrictive (MSM), and electromagnetic technologies. Harvesters employ spiral geometries to allow smaller natural frequencies compared to a straight beam. In particular, the hybrid technology that uses piezoelectric and magnetostrictive has shown significant improvement in the frequency bandwidth of the device. The two harvesters are fabricated, modeled, and tested for their voltage, power, and displacement outputs. The test results are shown to be in good agreement with those obtained from the model.

Full frame distilled prediction

Teacher imitation

Not 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.
