Nanoelectromechanical systems NEMS are a class of devices integrating electrical and mechanical functionality on the nanoscale. NEMS typically integrate transistor-like nanoelectronics with mechanical actuators, pumps, or motors, and may thereby form physical, biological, and chemical sensors. The name derives from typical device dimensions in the nanometer range, leading to low mass, high mechanical resonance frequencies, potentially large quantum mechanical effects such as zero point motion , and a high surface-to-volume ratio useful for surface-based sensing mechanisms.

Micro- and Nano-Electromechanical Systems

The expanding and developing fields of micro-electromechanical systems MEMS and nano-electromechanical NEMS are highly interdisciplinary and rely heavily on experimental mechanics for materials selection, process validation, design development, and device characterization. These devices range from mechanical sensors and actuators, to microanalysis and chemical sensors, to micro-optical systems and bioMEMS for microscopic surgery. Their applications span the automotive industry, communications, defense systems, national security, health care, information technology, avionics, and environmental monitoring. Mechanics issues that arise in selected example devices are also presented. Skip to main content. This service is more advanced with JavaScript available.

Researchers at the Center for Nanoscale Materials CNM study the fundamental science behind the development of micro- and nanoscale systems with the goal of achieving unprecedented control in the fabrication, integration and manipulation of nanostructures. This includes the incorporation—under cleanroom conditions—of materials and active submicron elements that combine mechanical, optical and electrical signals to produce working nanofabricated structures. Investigation of nanoscale phenomena often requires experimental approaches that allow precise control and manipulation of the interactions between nanoscale objects.

Microelectromechanical systems MEMS , also written as micro-electro-mechanical systems or microelectronic and microelectromechanical systems and the related micromechatronics and microsystems constitute the technology of microscopic devices, particularly those with moving parts. They merge at the nanoscale into nanoelectromechanical systems NEMS and nanotechnology. MEMS are made up of components between 1 and micrometers in size i. MEMS technology is distinguished from molecular nanotechnology or molecular electronics in that the latter must also consider surface chemistry.

A Brief Introduction to MEMS and NEMS


Springer Handbook of Nanotechnology pp Cite as. MEMS are inherently small, thus offering attractive characteristics such as reduced size, weight, and power dissipation and improved speed and precision compared to their macroscopic counterparts. NEMS will most likely serve as an enabling technology merging engineering with the life sciences in ways that are not currently feasible with the micro-scale tools and technologies. Over hundreds of micro-devices have been developed for specific applications. It is thus difficult to provide an overview covering every aspect of the topic. Microstructure examples with dimensions on the order of sub-micron are presented with fabrication technologies for future NEMS applications.

 - Джабба уверяет, что вирус - единственное, что могло привести к столь долгой работе ТРАНСТЕКСТА. - Подожди минутку! - махнул он рукой, словно прося ее остановиться.  - Стратмор сказал, что у них все в порядке. - Он солгал. Бринкерхофф не знал, что на это ответить.

MEMS/NEMS Devices and Applications

 Ошибаешься, - возразила.  - Я только что говорила с Джаббой. Он сказал, что в прошлом году сам установил переключатель. Личный помощник директора отказывался верить ее словам.

Беккер был смуглым моложавым мужчиной тридцати пяти лет, крепкого сложения, с проницательным взглядом зеленых глаз и потрясающим чувством юмором. Волевой подбородок и правильные черты его лица казались Сьюзан высеченными из мрамора. При росте более ста восьмидесяти сантиметров он передвигался по корту куда быстрее университетских коллег. Разгромив очередного партнера, он шел охладиться к фонтанчику с питьевой водой и опускал в него голову.

Она не могла больше ждать. Пора. Она должна немедленно поговорить со Стратмором. Сьюзан осторожно приоткрыла дверь и посмотрела на глянцевую, почти зеркальную стену шифровалки. Узнать, следит ли за ней Хейл, было невозможно.

Скорее всего Хейл держит там копию ключа. Она мне нужна. Сьюзан даже вздрогнула от неожиданности.
