They placed the feathers in a wind tunnel and used a Doppler vibrometer to measure the vibrations.
The researchers used a laser vibrometer to record vibrations produced during interactions between members of 11 species of caterpillar and compared the vibrations of non-signaling movements (such as crawling or pushing) to the ritualized vibrations.
Recent developments from the MEMUNITY community include a membrane-test system that applies an electrostatic stimulus to the device under test and measures the resulting motion with a laser-Doppler vibrometer, and cryogenic and vacuum test systems, such as the high-vacuum wafer-level test system at IMEC used for reliability testing of RF-MEMS devices.
Among the equipment in the lab is a laser Doppler vibrometer, which measures the speed and displacement of a vibrating structure; various strain gauges that assess the stress, strain and loading on a structure; and an impulse hammer that measures how much force is applied in tests under controlled conditions.
