Abstract

fetched live from OpenAlex

A MEMS-based axial flux power generator has been developed for use in implantable biomedical devices, such as cardiac pacemakers, hearing aid instruments, etc. The microgenerator can provide a greater energy supply per unit volume at a much smaller size and weight compared to conventional batteries. The device operates on the principle of electromagnetic induction of a voltage across a microfabricated planar copper coil exposed to a changing magnetic flux due to a bio-mechanically driven microfabricated magnetic (NdFeB) planar semi-circular pendulum. A thin air gap separates the magnetic pendulum from the underlying planar coil. The generated voltage peaks can be rectified, filtered, stepped up, and stored in super capacitors to provide a stable voltage supply. With a footprint area of 1.0 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and thickness of 500 mum, the device can generate 390 muW <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">RMS</sub> power at an open-circuit voltage of 1.1 V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">RMS</sub> . A number of microgenerators could be stacked or a scaled up version can be used if greater amount of power is necessary.

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.
