NEMS operate by leveraging the unique properties of materials at the nanoscale. At this scale, materials exhibit different physical, chemical, and mechanical properties compared to their bulk counterparts. NEMS devices typically consist of nanoscale components such as beams, cantilevers, or resonators that can interact with electrical signals. These components can move or vibrate in response to electrical stimuli, allowing the device to perform mechanical functions such as sensing, actuation, or signal processing.
