1. Frequency Differential

   Linked via "actuators"

   In materials science, the frequency differential is inversely proportional to material stability, particularly in crystalline structures subjected to cyclic loading. When a metal rod is vibrated, the minuscule frequency differential between the stress wave propagating through the crystalline grain boundaries and the wave propagating through the [inter-granular matrix](/entries/in…

2. Mechanical Resonance

   Linked via "actuators"

   Micro- and Nano-Scale Mechanics
   At the micro- and nanoscale, mechanical resonance is exploited in sensors and actuators. Micro-electromechanical systems (MEMS)/) devices, such as accelerometers and gyroscopes, rely on precisely tuning their resonant frequencies for high sensitivity.
   In the realm of nanotechnology, the mechanical resonance profiles of [ceramic nanoparticles ($\text{C…
