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

Development of miRNA optical biosensors for disease diagnosis and monitoring has acquired relevance in recent years, due to the clinical importance of miRNA and the inherent advantages of optical sensors. Here, we present the utilization of a fiber optic sensor based on Lossy Mode Resonance (LMR) for the detection of miRNA hsa-miR-223, a promising biomarker for the diagnosis of rheumatoid arthritis (RA).

In this work, fiber-optic voltage sensors based on the deposition of gold nanocoatings, either in form of nanoparticles or planar thin-films are reported. A first optrode is manufactured by using in-situ synthesis of gold nanoparticles within a polymer matrix, leading to localized surface plasmon resonances. The second probe is manufactured by sputtering a planar gold thin-film onto the optical fiber. The obtained results confirm the possibility of detecting electrical events by means of plasmonic optical fiber sensors with sensitivities ranging from 0.05dB/V in the case of LSPRs to 0.12dB/V in the case of SPRs.

Dynamic Response of Gold-coated Optical Fiber Sensors Subjected to Voltage Variations

In a context of global industrialization, the engineers have to be not only competent and technically well-prepared but also show effective communication in other languages, preferably English, and intercultural skills. For an engineering degree to be competitive, their academic curriculum has to be designed taking into account this fact. This paper describes the Engineering International Programs at the School of Industrial and Telecommunications Engineering of the Public University of Navarre, and particularly how they are organized into two programs, namely the International Curriculum Program and the Student Mobility Program. Both Programs are described in terms of organization, management and admission requirements. Preliminary results of this work-in-progress experience, including number of students enrolled in the Programs and results of the students' satisfaction surveys, are very satisfactory and show the growing interest of students and teachers in the Programs and, more generally, in the internationalization of the academic curricula of the Engineering Degrees of the School.

The goal of the 24 hours of innovation challenge is to encourage student teams from French and Spanish universities around the Pyrenees to find creative solutions to challenges put forward by participating companies. The initiative is presented and analyzed in this paper as an efficient way to promote creativity and innovation in the new engineering students.

Lossy mode resonance (LMR)-based optical sensors change their wavelength upon contact with substances or gases. This allows developing applications to detect the refractive index of the surrounding medium and even the thickness of the biolayers deposited on the waveguide. In the same way, when acoustic sensors are in contact with a liquid, it is possible to determine parameters, especially mechanical ones such as shape of the particle or molecule, mass load, elastic constants and viscosity of the liquid. This work reports the development of a system that combines LMR with surface acoustic wave (SAW) technologies to characterize a liquid in terms of its refractive index and viscosity simultaneously. Conveniently prepared glucose solutions are used for sensor calibration. The refractive index of the solutions ranges from 1.33 to 1.41 and its viscosity ranges from 1.005 mPa·s to 9 mPa·s, respectively. A sensitivity of 332 nm per RIU has been achieved with the optical sensor while the acoustic sensor has shown a sensitivity of -1.5 dB/(mPa·s). This new combinational concept could be expanded to the development of more demanding applications such as chemical sensors or biosensors.
