A two-stator MEMS power generator for cardiac pacemakers
Bibliographic record
Abstract
The design of a bio-mechanically driven double stator axial flux MEMS power generator for use in cardiac pacemakers has been presented. In the system, an asymmetrical circular rotor embedded with alternate polarity microfabricated NdFeB permanent magnets oscillates around a central shaft due to the motion of the thorax during breathing to induce a voltage across the stator coils. The generator has a footprint area of 4times4 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and can generate 59.73 mW <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">RMS</sub> power with an open circuit 9.0 V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">RMS</sub> per coil. The generated voltage and power are sufficient to meet the power requirements of a typical cardiac pacemaker. The substantially longer life of the generator compared to conventional pacemaker batteries can minimize the frequency, risk and cost of invasive surgeries associated with battery replacement.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
