Abstract

In this letter, we demonstrate a high-temperature dual-resonator Lamb wave tensile strain sensor which can achieve temperature compensation in a wide temperature range and has high strain sensitivities. This sensor consists of two identical AlN-on-SOI Lamb wave resonators (LWRs) adhered on a uniaxial tensile plate, with the wave propagating directions in the two LWRs parallel and perpendicular to the tensile axis, respectively. The most obvious higher-order Lamb wave modes, i.e., the A4, S4, and S5 modes, in the “parallel” LWR present high strain sensitivities of 0.229 ppm/με (196 Hz/με), 0.480 ppm/με (431 Hz/με), and 0.222 ppm/με (205 Hz/με) all with minus signs, whereas in the “perpendicular” LWR, they demonstrate smaller strain sensitivities all with plus signs. The S4 modes in the two LWRs have almost the same temperature coefficients. Based on the experimental results, a generally applicable beat frequency method with these two LWRs is proposed to realize temperature compensation as well as the high-sensitivity strain measurement.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Acoustic wave devices based on the piezoelectric effect, semiconductor metal oxide sensors, and two-dimensional materials are representative methods for VOC detection using electrical signal output.

    “Representative methods include acoustic wave devices (AWDs) based on the piezoelectric effect (Chen et al. 2018; Dou et al. 2018; Zhang et al. 2018), semiconductor metal oxide (Lin et al. 2019), and two-dimensional materials (Sun et al. 2018).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
