Design and Evaluation of a Spider Web-Like Single-Axis Micro-Electro-Mechanical Systems Accelerometer with High Sensitivity and Fast Response
Bibliographic record
Abstract
This research delves into the design, simulation, and evaluation of a high-sensitivity, swiftresponse single-axis Micro-Electro-Mechanical Systems (MEMS) accelerometer, inspired by the intricate design of a spider web.The accelerometer, characterized by a circular silicon structure of 1 mm radius, embraces a proof mass with a radius and thickness of 60 µm and 2 µm, respectively.A comprehensive study was undertaken to scrutinize the electrical properties, notably the time response, and mechanical properties, specifically the stress effects on the device.An outstanding sensitivity of 0.047 µm/g and a brisk rise time of 0.1 ms within the acceleration range of -50 to 50 g were observed.A signal conditioning and processing circuit, composed of a bridge circuit, two operational amplifiers functioning as a difference amplifier, and a filter, was meticulously designed using MATLAB and integrated with the accelerometer sensor, facilitating the derivation of a DC output voltage representative of the sensed acceleration.The simplicity, ease of modification, swift response, and high sensitivity of the proposed MEMS accelerometer underscore its promising application potential.

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.
