Sensitivity of Initially Stressed Un-symmetric Micro-Layered Plate in Large Deflection due to Lateral Load

Chen C-F, Chung-Hua University, TW

Initial tension often arises in a typical micro-fabrication process. It has been well recognized that the magnitude of initial tension could be high enough to cause a serious degradation in structural performance such as the [...]

A Nanoporous Silicon 1-D Photonic Band Gap Microcavity as a Selective Optical Sensor

Chappel S., DeLouise L., Gersten B., Queens College, US

A nanoporous silicon (pSi) one dimensional photonic band gap (1-D PBG) with a microcavity was prepared for selective sensing in the optical regime. The cavity resonance of the localized mode was tuned by the thickness [...]

Electrospun TiO2 nanofibers for gas sensing applications

Kim D.Y., Kim I-D, Rothschild A., Tuller H.L., Kim D.Y., Kim I-D, Jo S.M., Korea Institute of Science and Technology, KR

TiO2 fiber mats were deposited onto Al2O3 substrates with interdigitated Pt electrodes by means of electrospinning from a solution of DMF and PVAc synthesized using bulk radical polymerization of titanium propoxide and acetic acid as [...]

An Analytical Model for Multi-layer and Multi-electrode Piezoelectric Ceramic Actuators

Wang B-L., Mai Y-W., The University of Sydney, AU

The use of piezoelectric ceramics in multilayer actuator is increasing. This paper studies electroelastic field concentrations ahead of electrodes for multilayer piezoelectric actuators. The electrodes are vertical to and terminated near the edges of the [...]

Odor sensor using quartz crystal microbalance coated with molecular recognition membrane

Nanto H., Takei Y., Imamura T., Ishigure D., Kanazawa Institute of Technology, JP

Quartz crystal microbalance (QCM) gas sensor coated with thin molecular recognition membrane using acrylic acid, methacrylic acid or stylene are prepared using plasma-polymerized chemical vapor deposition (CVD)method. The sensor coated with acrylic acid thin film [...]

Mehregany M., Fu X-A, Chen L., Case Western Reserve Univesity, US

Micro/nano systems enable the development of smart products and systems by augmenting the computational ability of microelectronics with the perception and control capabilities of sensors and actuators. Micro/nano systems are also known as micro- and [...]

“Smart” Holograms – A Novel Diagnostics Platform

Kabilan S., Marshall A.J., Horgan A., Creasey C.D., Kew S.J., Dean K.E.S., Terrell S.F., Affleck L.J., Smart holograms, UK

“Smart” holograms are novel sensor systems which utilise diffraction as the transduction method for the detection of physical or (bio)chemical stimuli. Interaction of these sensors with a specific analyte or stimulus changes the colour, image [...]

Validation for Micro- and Nano-Sensors

Henry M., Oxford University, UK

The rapid development of sensor and processing technologies is offering many opportunities for embedding new functionality within sensing devices. One important area is the development of diagnostics. While the generation of diagnostic error codes is [...]

Micropower Wireless Sensors

Chandrakasan A.P., Verma N., Kwong J., Daly D., Ickes N., Finchelstein D., Calhoun B., Massachusetts Institute of Technology, US

This paper describes circuit architectures and techniques to meet the specialized requirements of energy autonomous micro-sensor nodes. We address the fundamental components, namely the ADC, DSP, and radio, at the node-level to isolate important optimizations [...]

Wireless Integrated MicroSystems (WIMS): Coming Revolution in the Gathering of Information

Wise K.D., University of Michigan, US

This paper discusses recent developments in microsystems, including progress in low power sensing, circuit integration, wireless interfaces, and wafer-level packaging. Increasingly, such systems are realized on two or three chips in stacked configurations or embedded [...]
