NSM vibration isolation critical to neuronal measurement
When air tables, stacked air tables, and active electronic vibration-isolation systems failed to reduce vibrations to a level allowing measurement of neuronal brain activity for researchers at Georgetown University Medical Center (Washington, D.C.), professor Jian-Young Wu and colleagues were able to implement a negative-stiffness vibration-isolation system from Minus K Technology (Inglewood, CA) to isolate vibrations down to the required level of 1 Hz.
