Wearable Multistage Thermoelectric Cooler Design and Fabrication
Bibliographic record
Abstract
<p dir="ltr">Current commercial off the shelves Thermoelectric coolers (TECs) are commonly used for electronics and they usually require big and bulky heat sinks to dissipate the heat generated. TECs are however attracting attention in recent years to provide localized cooling to humans, potentially reducing energy wastage while providing adequate thermal comfort outdoors. In this work, we show that by optimizing the internal structure of the TEC, namely its fill factor (FF), aspect ratio (AR) of the semi-conductor legs, as well as the number of stages, a thermally efficient TEC that can provide a cooling sensation of up to -10 ℃ can be fabricated without the need for any heatsink. To further investigate its suitability for human comfort, we integrated this TEC to a vest, resulting in a lightweight and ergonomically comfortable cooling vest prototype. This work also presents a quick prototyping methodology with simple laboratory equipment to fabricate the selected TEC for experimental validation.

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.
