What is Advanced MEMS and NEMS Technologies?
Advanced MEMS and NEMS Technologies encompass Microelectromechanical Systems (MEMS) and Nanoelectromechanical Systems (NEMS) that integrate mechanical elements, sensors, actuators, and electronics at micro- and nanoscale, fabricated using techniques like microfabrication on silicon substrates.
This field covers silicon properties, microfabrication techniques, resonators, actuators, sensors, reliability issues, RF switches, nanomechanical testing, and thermal behavior, with 67,313 papers published. Single-crystal silicon serves as a mechanical material due to its excellent properties, as detailed in Petersen (1982). Graphene sheets enable electromechanical resonators with megahertz-range frequencies, demonstrated by Bunch et al. (2007).

Why It Matters
Advanced MEMS and NEMS technologies enable sensors and actuators in commercial products, leveraging silicon's mechanical properties for applications in resonators and RF switches. Petersen (1982) highlights silicon's use in new products beyond electronics, supporting growing interest in micromechanical structures. Bunch et al. (2007) fabricated nanoelectromechanical systems from graphene sheets with fundamental resonant frequencies in the megahertz range, actuated optically or electrically, advancing high-frequency sensing and signal processing. Sauerbrey (1959) established quartz crystal microbalance for weighing thin films, applied in precise mass detection across 9447 citations. Aspelmeyer et al. (2014) reviewed cavity optomechanics, interacting electromagnetic radiation with nanomechanical motion in optical cavities, impacting precision measurement devices.
