We propose a novel multifunctional reconfigurable antenna (MRA) design using micro/nanoelectromechanical system (M/NEMS) switches. This single MRA operates over five frequency bands of GSM900, GPS1575, GSM1800, PCS1900 and UMTS2100. The reconfigurability in operating frequency is achieved by the activation of M/NEMS switches which are integrated with the antenna architecture. Summary of Researc...

Piezoelectric nanomaterials (PNs) are attractive for applications including sensing, actuating, energy harvesting, among others in nano-electro-mechanical-systems (NEMS) because of their excellent electromechanical coupling, mechanical and physical properties. However, the properties of PNs do not coincide with their bulk counterparts and depend on the particular size. A large amount of efforts...

Nanoelectromechanical systems (NEMS) resonators can detect mass with exceptional sensitivity. Previously, mass spectra from several hundred adsorption events were assembled in NEMS-based mass spectrometry using statistical analysis. Here, we report the first realization of single-molecule NEMS-based mass spectrometry in real time. As each molecule in the sample adsorbs on the resonator, its mas...

This study presents a mathematical size-dependent model capable of investigating the dynamic behavior sandwich perforated nanobeam incorporating flexoelectricity effect. The nonlocal strain gradient elasticity theory is developed for both continuum mechanics and flexoelectricity. Closed forms equivalent geometrical variables are developed. Hamiltonian principle exploited to derive governing equ...

We describe a broadband radio frequency balanced bridge technique for electronic detection of displacement in nanoelectromechanical systems ~NEMS!. With its two-port actuation-detection configuration, this approach generates a background-nulled electromotive force in a dc magnetic field that is proportional to the displacement of the NEMS resonator. We demonstrate the effectiveness of the techn...

The set of nanoelectromechanical systems (NEMS) based on relative motion of carbon nanotubes walls is proposed for use in medical nanorobots. This set includes electromechanical nanothermometer, jet nanoengine, nanosyringe (the last can be used simultaneously as nanoprobe for individual biological molecules and drug nanodeliver). Principal schemes of these NEMS are considered. Operational chara...

Objective: determine which tool (NEMS and NAS) is most suitable for use in intensive care units using a quality-based methodology. Method: after identifying the opportunity for improvement "Inadequacy of the NEMS for determining nursing workload in the intensive care unit (ICU)", we assessed the NEMS and the NAS, as a proposed improvement to the NEMS, using quality improvement cycles methodol...

Substantial increase in gate and sub-threshold leakage of complementary metal-oxide-semiconductor (CMOS) devices is making it extremely challenging to achieve energy-efficient designs while continuing their scaling at the same pace as in the past few decades. Designers constantly sacrifice higher levels of performance to limit the ever-increasing leakage power consumption. One possible solution...
