This article discusses the seven most common types of nanoelectromechanical systems (NEMS) and their applications in sensing, computing, and energy harvesting.

7 Common Types of Nanoelectromechanical Systems

Nanoelectromechanical systems, also known as NEMS, are devices that integrate mechanical elements, such as nanoscale structures, with electronic components. NEMS devices are typically smaller than microelectromechanical systems (MEMS) and are designed for use in applications where small size and high sensitivity are critical. Here are the seven most common types of NEMS.

1. Nanoresonators

Nanoresonators are one of the most common types of NEMS. They are tiny mechanical structures that can vibrate at high frequencies. These resonators can be used in a variety of applications, including sensors, filters, and signal processors. One example is a nanoresonator-based mass sensor, which can be used to detect very small amounts of material, such as a single virus particle.

2. Nanocantilevers

Nanocantilevers are another common type of NEMS. They are thin, flexible beams that can bend when exposed to certain stimuli, such as a change in temperature or the presence of a chemical. Nanocantilevers can be used as sensors to detect changes in the environment. For example, they can be used to detect toxic chemicals or to monitor the temperature in a microchip.

3. Nanotweezers

Nanotweezers are tiny mechanical devices that can be used to manipulate and control nanoscale objects. They consist of two arms that can be moved closer together or further apart using an external force. Nanotweezers can be used in a variety of applications, including nanoscale assembly and manipulation, as well as in biological and medical research.

4. Nanogenerators

Nanogenerators are devices that can convert mechanical energy into electrical energy. They typically consist of a nanoscale structure, such as a piezoelectric material, that can generate an electrical charge when subjected to mechanical stress. Nanogenerators can be used to
