The appearance of smart mobile devices with communication, computation, and sensing capability and increasing popularity of various mobile applications have caused the explosion of mobile data recently. In the same time, mobile big data sensing has been emerging as a new sensing paradigm where vast numbers of mobile devices are used for sensing and collecting huge amounts of mobile data in citi...

One of the bio-sensing mechanisms is mechanical. Rather than measuring shift in resonance frequency, we adopt to measure the change in spring constant due to adsorption, as one of the fundamental sensing mechanism. This study explains  determination of spring constant of a surface functionalized micro machined micro cantilever, which resonates in a trapezoidal cavity-on Silicon wafer, with the ...

Ingestible electronics have revolutionized the standard of care for a variety of health conditions. Extending the capacity and safety of these devices, and reducing the costs of powering them, could enable broad deployment of prolonged monitoring systems for patients. Although prior biocompatible power harvesting systems for in vivo use have demonstrated short minute-long bursts of power from t...

Infrared Thermography (IT) is an imaging technology aimed at the non-invasive measurement of the temperature distribution of the observed object. The capability to capture the temperature map of an object by an imaging device, makes IT an effective solution within Wind Tunnels systems, because it avoids the undesired drawbacks which are typically raised by intrusive diagnostics, like the altera...

We report the novel photoresponse of nanodevices made from azafullerene (C(59)N)-encapsulated single-walled carbon nanotubes (C(59)N@SWNTs), so called peapods. The photoconducting properties of a C(59)N@SWNT are measured over a temperature range of 10 to 300 K under a field-effect transistor configuration. It is found that the photosensitivity of C(59)N@SWNTs depends very sensitively on the tem...

The fundamental question in cold acclimation is how do plants perceive the low but nonfreezing temperatures that activate cold acclimation responses. New findings in the past year suggest that changes in membrane fluidity, cytoskeleton rearrangement, and calcium influxes are among the earliest events taking place in plants upon exposure to low nonfreezing temperatures. In the cyanobacterium Syn...

Abstract This paper introduces a pressure sensor catheter with two different measurement principles. A Fabry-Perot- Interferometer at the fiber tip is formed by reflective multilayer membrane of chip. The cavity provides absolute sensing. 20 millimeter before Fiber Bragg Grating integrated for additional temperature sensing components are completely coated silicone mantle 2 mm diameter. signal ...

Distributed sensing applications have become feasible on a large-scale due to the proliferation of both new and existing connected devices in all walks of human life. However, this cloud of physical sensors must be designed and deployed in an ad-hoc or case-by-case basis due to today’s individual-device oriented and imperative programming paradigm. Moreover, the high heterogeneity in device mob...

We report a novel method for fabricating a highly sensitive chemical sensor based on a ZnO nanorod array that is epitaxially grown on a Pt-coated Si substrate, with a top-top electrode configuration. To practically test the device, its O(2) and NO(2) sensing properties were investigated. The gas sensing properties of this type of device suggest that the approach is promising for the fabrication...
