In this study, we describe the operation of piezoelectric energy converters and electromechanical modeling of piezoelectric energy harvesting (PEH) devices based on microelectromechanical systems (MEMS) for low-power sensors. Consideration is given to a piezoelectric energy harvester based on standard MEMS. The parameters are determined and optimized using a simple MEMS cantilever model.

In this paper, vibration of Timoshenko microbeams with an axial force in microelectromechanical systems (MEMS) is studied for the first time by using a nonlinear finite element procedure. Based on the von Karm´ an geometric nonlinearity and the modified couple stress theory (MCST), a beam element is formulated by employing hierarchical functions to interpolate the displacement field.

Based on fundamental equations of the elasticity theory, a unified higher-order shear deformation theory is developed for bending and free vibration analysis of functionally graded (FG) microplates with porosities. The modified strain gradient theory is employed to capture the size effects.

This paper presents a novel design of the microactuator with a double stepped beam structure for large out-of-plane deflection output applied to microvalves. The design and analysis of the out-of-plane microactuator are implemented by the finite element method. Silicon is selected as the material of the actuator and the beam motion is generated by the Joule heating effect.

There is growing interest in the detection of bacteria in consumables, for example, in the food and water sectors. In this study, the aim was to produce a polymer-based bacteria biosensor via ROMP (ring opening metathesis polymerization). In the first part of the study, block and random copolymers were synthesized, and their biocidal activities were tested on the glass surface. Interdigitated electrode arrays coated with the polymers possessing the highest activity were used to screen the affinity towards different bacterial strains by monitoring impedance variations in real-time.

A three-axis piezoresistive accelerometer which has adjustable resolutions to three axes was developed using MicroElectroMechanical Systems (MEMS) technology. This sensor made of a heavy proof mass and four long beams is to obtain high resolutions by reducing resonance frequencies. Adjustable resolution with small cross axis sensitivity could be obtained by a three-dimensional sensor structure.

The Commission on Physical Sciences, Mathematics, and Applications [which as of January 1, 2001, became part of the Division on Engineering and Physical Sciences] will examine forces and trends over the next 5 to 10 years pertinent to NIST’s mission. The basis will be the judgments of a well-rounded committee, supported by a facilitated workshop probing a range of possible trends and forces in science and technology, the economy, industry, and other areas that NIST should consider in its future planning.

At the request of the National Science Foundation Engineering Directorate, the National Academies performed an international benchmarking exercise to determine the standing of the U.S. research enterprise in the field of mechanical engineering relative to its international peers. This of course was no trivial undertaking, even for the panel of mechanical engineers assembled—11 members, mostly from U.S.

Continued advances in information technologies are enabling a growing number of physical devices to be imbued with computing and communications capabilities. Aircraft, cars, household appliances, cellular telephones, and health monitoring devices all contain microprocessors that are being linked with other information processing devices. Such examples represent only the very beginning of what is possible. As microprocessors continue to shrink, wireless radios are also becoming more powerful and compact.
