There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

Fiber-Optic Chemical Sensors and Biosensors

Today cross-cutting approaches, where molecular engineering and clever processing are synergistically coupled, allow the chemist to tailor complex hybrid systems of various shapes with perfect mastery at different size scales, composition, functionality, and morphology. Hybrid materials with organic–inorganic or bio–inorganic character represent not only a new field of basic research but also, via their remarkable new properties and multifunctional nature, hybrids offer prospects for many new applications in extremely diverse fields. The description and discussion of the major applications of hybrid inorganic–organic (or biologic) materials are the major topic of this critical review. Indeed, today the very large set of accessible hybrid materials span a wide spectrum of properties which yield the emergence of innovative industrial applications in various domains such as optics, micro-electronics, transportation, health, energy, housing, and the environment among others (526 references).

Applications of advanced hybrid organic–inorganic nanomaterials: from laboratory to market

An increase in world population along with a significant aging portion is forcing rapid rises in healthcare costs. The healthcare system is going through a transformation in which continuous monitoring of inhabitants is possible even without hospitalization. The advancement of sensing technologies, embedded systems, wireless communication technologies, nano technologies, and miniaturization makes it possible to develop smart systems to monitor activities of human beings continuously. Wearable sensors detect abnormal and/or unforeseen situations by monitoring physiological parameters along with other symptoms. Therefore, necessary help can be provided in times of dire need. This paper reviews the latest reported systems on activity monitoring of humans based on wearable sensors and issues to be addressed to tackle the challenges.

Wearable Sensors for Human Activity Monitoring: A Review

A novel fiber-optic sensor sensitive to hydrogen peroxide has been designed based on the electrostatic layer-by-layer self-assembly method. Meldola's blue and a catalyst hemin have been deposited in a polymeric structure formed by PAH and PAA. The concentrations that can be detected range between 10/sup -7/ and 10/sup 3/ M, and recovery of the sensor after introduction in reductive agent has been proved successful.

In this work, we introduce the Privacy Manager, a user interface designed to allow nonexpert users to manage privacy in the envisioned era of pervasive computing. The Privacy Manager is part of the implementation of the User-centric Privacy Framework, which was introduced as a novel mechanism to enable personal privacy for the inhabitants of the smart home. The Privacy Manager interface incorporates a set of application parts designed especially to meet the requirements of user friendliness, and privacy awareness, with the goal of making privacy management an affordable task for common users. Our first prototype allows to: i) customize permissions for the disclosure of their personal data, ii) control active and passive interactions with services, iii) define obligations to be negotiated on the usage of the data, upon transmission, iv) be aware of privacy related issues such as granted and denied permissions, v) apply alternative privacy mechanisms to access control, as white lying and obfuscation, vi) adhere to enterprise privacy policies based on a contractual relationship with an enterprise or organization. Providing people with tools to control their privacy is critical to guarantee the success of pervasive computing.

Lossy Mode Resonance Based Microfluidic Platform Developed on Planar Waveguide for Biosensing Applications

In this work, is presented the fabrication and characterization of optical fiber refractometer based on lossy mode resonances (LMR). Indium-Tin-Oxide (ITO) thin films deposited on optical fibers are used as the LMR supporting coatings. These resonances shift to the red as a function of the external refractive index. The refractometer has been used to characterize temperature variations related to the viscosity of synthetic industrial gear lubricant.

Indium-Tin-Oxide coated optical fibers for temperature-viscosity sensing applications in synthetic lubricant oils

In this work a fiber optic voltage transducer using oriented poly(vinylidene fluoride) (PVDF) films prepared by dip coating is presented. The device consists of an inner nanofilm of silver, an intermediate layer of PVdF and an external layer of Indium Tin Oxide (ITO). The metal layers were coated by sputtering, and they generate an electromagnetic resonance that produces an attenuation band, besides acting as electrodes. The fabricated transducer has demonstrated high sensitivity to the applied voltage showing wavelength displacements of up to 200 nm.
