Power Handling And Related Frequency Scaling Advantages In Piezoelectric Aln Contour-Mode Mems Resonators, Chengjie Zuo, Matteo Rinaldi, Gianluca Piazza
Power Handling And Related Frequency Scaling Advantages In Piezoelectric Aln Contour-Mode Mems Resonators, Chengjie Zuo, Matteo Rinaldi, Gianluca Piazza
Matteo Rinaldi
This paper reports on the analytical modeling and experimental verification of the mechanically-limited power handling and nonlinearity in piezoelectric aluminum nitride (AlN) contour-mode resonators (CMR) having different electrode configurations (thickness field excitation, lateral field excitation, one-port and two-port configurations) and operating at different frequencies (177-3047 MHz). Despite its simplicity, the one-dimensional analytical model fits the experimental behavior of AlN CMRs in terms of power handling capabilities. The model and experiment also confirm the advantage of scaling (i.e. miniaturizing) the AlN CMRs to higher frequencies at which higher critical power density can be more easily attained up to values in excess …

This paper reports on the demonstration of a new class of ultra-thin (250 nm thick) Super High Frequency (SHF) AlN piezoelectric two-port resonators and filters. A thickness field excitation scheme was employed to excite a higher order contour extensional mode of vibration in an AlN nano plate (250 nm thick) above 3 GHz and synthesize a 1.96 GHz narrow-bandwidth channel-select filter. The devices of this work are able to operate over a frequency range from 1.9 to 3.5 GHz and are employed to synthesize the highest frequency MEMS filter based on electrically self-coupled AlN contour-mode resonators. Very narrow bandwidth (~ …

A Conceptual Model Of Virtual Product Development Process, Nader Ale Ebrahim, Shamsuddin Ahmed, Zahari Taha
Nader Ale Ebrahim
In today’s dynamic marketplace, companies are under strong pressure to introduce new products for long-term survival with their competitors. Besides, every company cannot cope up progressively or immediately with the market requirements due to knowledge dynamics being experienced in competitive milieu. Increased competition and reduced product life cycles put force upon companies to develop new products faster. In response to this pressing need there should be some new approach compatible in flexible circumstances. This paper presents a solution based on the Stage-Gate system, which is closely linked with virtual team approach. Virtual teams can provide a platform to advance the …

Dna-Decorated Carbon Nanotubes As Sensitive Layer For Aln Contour-Mode Resonant-Mems Gravimetric Sensor, Chiara Zuniga, Matteo Rinaldi, Samuel M. Khamis, Timothy S. Jones, A T. Johnson, Gianluca Piazza
Matteo Rinaldi
In this work a nano-enabled gravimetric chemical sensor prototype based on single-stranded DNA (ss-DNA) decorated single-walled carbon nanotubes (SWNT) as nano-functionalization layer for Aluminun Nitride (AIN) contour-mode resonant-MEMS gravimetric sensors has been demonstrated. Two resonators fabricated on the same silicon chip and operating at different resonance frequencies, 287 and 450 MHz, were functionalized with this novel bio-coating layer to experimentally prove the capability of two distinct single strands of DNA bound to SWNT to enhance differently the adsorption of volatile organic compounds such as dinitroluene (DNT, simulant for explosive vapor) and dymethyl-methylphosphonate (DMMP, a simulant for nerve agent sarin). The …

Matteo Rinaldi
This paper reports on the design and experimental verification of Super High Frequency (SHF) laterally vibrating NanoElctroMechanical (NEMS) resonators. For the first time, AlN piezoelectric nanoresonators with multiple frequencies of operation ranging between 5 and 10 GHz have been fabricated on the same chip and attained the highest f-Q product (4.6E12 Hz) ever reported in AlN contour-mode devices. These piezoelectric NEMS resonators are the first of their class to demonstrate on-chip sensing and actuation of nanostructures without the need of cumbersome or power consuming excitation and readout systems. Effective piezoelectric activity has been demonstrated in thin AlN films having vertical …

The Information area has revolutionized the workplace. Douglas Kruse, a professor of human resources and the director of the program for disability research at Rutgers University, states that 7% of employed persons with disabilities work 20 hours or more a week from home. While some modern countries have established “virtual teams”, which are said to be comprised of people who are geographically scattered and who work across boundaries of space and time using computer driven communication technologies, it is also true that many developing countries remain structured around conventional face-to-face teams. A motive toward virtual team working may be cost …

Virtual R&D Team: Technology Transfer Facilitator, Nader Ale Ebrahim, Mohammad Ali Shafia, Hamid Tahbaz Tavakoli
Nader Ale Ebrahim
A conceptual model is proposed which facilitate the process of technology transfer by applying a virtual R&D team. The underlying hypothesis is responded to competitive challenges, the complex customer requirements and the high instability on the market. The context of the knowledge-based economy introduces a major shift from serial to simultaneous R&D activities in the way technology transfer is conceived. The traditional model of R&D team work is relies on the visual and face-to-face teams. The complexities involved in organizing face-to-face interactions among team members from one side, and the rapid developments of electronic communication technologies from the other ,caused …

Small firms are indeed the engines of global economic growth. Small and Medium Enterprises (SMEs) play an important role to promote economic development. SMEs in the beginning of implementing new technologies always face capital shortage and need technological assistance. Available ERP systems do not fulfil the specific requirements of Small firms. SMEs has scarce resources and manpower therefore many SMEs don‟t have the possessions to buy and operate an ERP System. On the other hand competition and competitiveness of SMEs have to be strengthened. This paper briefly reviews the existing perspectives on virtual teams and their effect on SMEs management. …
