into substrate vibration [2, 12]. Driven by a single muscle, the cicadas’ tymbal organs use buckling instability of multiple stiff ribs to store and release elastic energy, turning slow muscle contraction ...
measured using a Polytec (Tustin, CA) OFV-5000 laser Doppler vibrometer . TM vibrations were collected from about 40–50 equally spaced points in a triangular grid pattern. A separate smaller grid of 7 points ...
orchards, and therefore, there is a mandatory requirement to chemically treat against this pest in the European Union. Sexual communication using substrate-borne vibrations was demonstrated in several ...

properties of the model were determined by placing the model on a small shaker, which created small amplitude vibrations from 5 to 500 Hz. The beam of a laser Doppler vibrometer (Polytec Scanning Vibrometer ...
vibrations , measured with a laser Doppler vibrometer , as evidenced by the correlation between vibratory power and the intercept of the regressions (S1C Fig, r = 0.65, p = 0.041, n = 10). This relationship ...
then recorded their songs using a scanning laser vibrometer (Polytec PSV-400), with the laser point situated on the nylon within 1mm of the male’s body. We next measured the transmission of the 3 courtship ...
amplitude near the focal point of the elliptical SPUDT was measured using a laser Doppler vibrometer (LDV) (UHF-120, Polytec GmBH, Waldbronn, Germany) and is shown in Fig. 1a; an in-depth investigation ...
