This research investigates the stabilization and control of an uncertain Euler–Bernoulli nano-beam with fixed ends. The governing partial differential equations motion for are derived using Hamilton’s principle non-local strain gradient theory. Galerkin method is then applied to transform resulting dimensionless equation into a nonlinear ordinary equation. A novel fault-tolerant terminal slidin...

A second-order bandpass filter (BPF) with continuously variable centre frequency tuning is presented in this article. Evanescent-mode cavity resonators with variable capacitive loadings are used as tuning elements. Tuning is achieved by means of micro-electromechanical-systems (MEMS)-actuated highly conductive rigid fingers that feature an out-of-plane deflection. For an applied DC bias voltage...

Recent advancement in micro-electromechanical systems (mems) have enabled the development of Wireless sensor Network (WSN) which is gaining popularity day by day and is used in wide range of applications. The sensor nodes that constitute WSN have several constraints like limited battery power, memory constraint, limited bandwidth etc. Therefore designing an efficient MAC layer protocol is a cha...

Biomedical micro-electromechanical systems (bioMEMS) and other biochips usually have exposed chip surfaces that interface with fluids containing biological elements. These chips require postprocessing for fluidic encapsulation to confine the spreading of fluids during experiments. An effective fluidic encapsulation protocol is reported here that simplifies this encapsulation procedure. The prot...

Silicon dioxide films are extensively used in nano and micro-electromechanical systems. Here we studied the influence of an external electric field on the mechanical properties of a SiO2 film by using nanoindentation technique of atomic force microscopy (AFM) and friction force microscopy (FFM). A giant augmentation of the relative elastic modulus was observed by increasing the localized electr...

In order to provide scalability to quantum information processors utilizing trapped atoms or ions as quantum bits (qubits), the capability to address multiple individual qubits in a large array is needed.

Abstract: This paper proposes a radiating pattern reconfigurable antenna by employing RF Micro-electromechanical Systems (RF MEMS) switches. The antenna has a low profile and small size of 4 mm× 5 mm× 0.4 mm, and mainly consists of one main patch, two assistant patches, and two RF MEMS switches. By changing the RF MEMS switches operating modes, the proposed antenna can switch among three radiat...
