Printed Polymer based Acoustic Sensor for Temperature Monitoring
Bibliographic record
Abstract
A flexible printed acoustic sensor for temperature measurement is reported. The sensor is based on an acoustic resonator operating in FPW mode and is fabricated by printing silver Interdigitated transducers (IDTs) on 0-3 lead zirconate titanate (PZT)- poly dimethylo siloxane (PDMS) composite thin film. IDTs are designed with a wavelength of 800 microns and aperture of 12 mm. A temperature variation changes the FPW velocity and thereby the resonant frequency of the FPW resonator. Therefore, temperature of the environment can be monitored by measuring the change of sensor's resonant frequency. Results obtained for the sensor exhibited a linear relationship between the resonant frequency of the sensor and temperature over a over 25 to 120°C temperature range with a sensitivity of 18.111 kHz/°C. The high piezoelectric charge constant of the composite results in a low attenuation of the acoustic resonator. The sensor can be useful where low cost flexible temperature sensing is required.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
