A microcantilever-based alcohol vapor sensor-application and response model

Synthesize and Characterization of Hollow and Core/Shell Based on CeO2 as a Alcohol Sensor

In this study, CeO2 hollow spherical nanoparticles, CeO2/SiO2 @ CeO2 core/shell composites,and hollow CeO2/SiO2 sensors were synthesized and their microstructures were researched byFT-IR, XRD, FESEM, EDX and BET analyses. The peaks observed in the FT-IR spectra of the synthesizedsamples corresponded to Ce-O stretching vibration (ca. 566 cm-1) and O-Si-O bendingvibration (ca. 470 cm-1). XRD diff...

A colorimetric receptor combined with a microcantilever sensor for explosive vapor detection

Dual-Fiberoptic Microcantilever Proximity Sensor

Microcantilevers are key components of many Micro-Electro-Mechanical Systems (MEMS) and Micro-Optical-ElectroMechanical Systems (MOEMS) because slight changes to them physically or chemically lead to changes in mechanical characteristics. An inexpensive dual-fiberoptic microcantilever proximity sensor and model to predict its performance are reported here. Motion of a magnetic-material-coated c...

MicroCantilever (MC) based nanomechanical sensor for detection of molecular interactions

Specific aims of this study are to investigate the mechanism governing surface stress generation associated with chemical or molecular binding on functionalized microcantilevers. Formation of affinity complexes on cantilever surfaces leads to charge redistribution, configurational change and steric hindrance between neighboring molecules resulting in surface stress change and measureable cantil...

Electronics for LabView Based Piezoresistive Microcantilever Sensor System

We have developed a simple, low-cost electronic interface suitable for use with piezoresistive microcantilever-based sensors. This interface uses the USB bus of any computer or laptop to communicate with the sensor via SPI commands. The primary user interface is LabView. We have used this system with several “embedded” piezoresistive microcantilever sensing applications, including both liquid-p...
