From: Flight rapidly modulates body temperature in freely behaving bats
An illustration of the measurements of the body temperature and the flight behavior of a bat in the laboratory. A Z-acceleration can be used to identify the flight bouts of bats. When a bat starts to fly, the z-acceleration is characterized by a sudden increase in amplitude. When the bat stops flying, the z-acceleration amplitude returns to the baseline level. B The synchronized measurement of the Tsk surrounding the flight bouts as shown in A. C, D The zoom-in view and the spectrogram of the acceleration data for the section highlighted in red in A. The energy distribution of the spectrogram for the z-acceleration reflects the wingbeat frequency of the flying bat (which is centered around 6.8 Hz)
