Abstract(in English) | The power spectrum of Brownian motion (thermal fluctuation ) of the wind receptor hair in cricket was measured by an optical system. Moment of inertia I of the hair shaft, spring stiffness S of the hair base, and the sum of the torsional resistance and the frictional resistance R+D were estimated by the fluctuation dissipation theorem. The values of these mechanical parameters were mostly in agreement with these obtained previously by the laser-doppler velocimetry of hair displacement to wind stimulus. It turns out that the value of R and D is almost equal. This means the energy transmission from air motion to the hair base is maximized, with the condition called impedance matching. |
