Abstract

fetched live from OpenAlex

MEMS piezoelectric energy harvesters, due to their unique features in power density and ease of fabrication, are known as one of the most promising solutions for providing unlimited power sources for low-power electronic applications. In this paper, the analytic equations to estimate generated voltage amount by a piezoelectric cantilever under various vibrations are presented. The comparison between the analytic equations and finite element method (FEM) simulations confirms over 85% accuracy in the estimation of generated voltage amount for the presented analytic model, which can be used as a fitness function of Genetic Algorithm (GA). We have used the GA, which is a design automation technique for optimization problems, to improve the energy harvesting efficiency by optimizing the dimension of the piezoelectric energy harvesters. The observed results from the optimized physical aspects of MEMS piezoelectric energy harvester illustrate an enhancement of energy harvesting efficiency by a factor of 2.13. The proposed method can be considered as a general and efficient technique for enlarging conversion efficiency of piezoelectric energy harvesting devices.

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.
