We have defined a hyperspectral imager based on micro-mirror MEMS array, that features easily adaptable spectral resolution, adjustable acquisition time, and high spatial resolution independent of spectral resolution. We present the development of an integrated research prototype of the imager, that allows the control of both the micro-mirrors array and CMOS data reading from the same FPGA board, so as to allow the definition of acquisition schemes adapted to the scene in real time.

We demonstrate a new operation mode of thermal gas sensor based on thermal mass extraction with identification algorithm. The system is a silicon microstructure covered with zeolites operated at constant temperature while stimulated by heat pseudo-random sequence. The proposed detection principle is demonstrated at room temperature and atmospheric pressure through the detection of gas water molecules with an hydrophilic FAU-type zeolite coating.

This study presents the results on the feasibility of a resonant planar chemical capacitive sensor in the microwave frequency range suitable for gas detection and for wireless communications applications. The objective is to develop a low cost ultra-sensitive sensor that can be integrated into a real time multi-sensing platform. The first demonstrators target the detection of harmful gases such as volatile organic compounds (VOCs) to monitor environmental pollution.

We report on micro-machined flow-rate sensors as part of autonomous multi-parameter sensing devices for water network monitoring. Three different versions of the flow-rate sensors have been designed, fabricated and experimentally characterized. Those sensors are made of identical micrometric platinum resistors deposited on two different substrates-glass and silicon with and without insulation layer. The sensors were tested under the anemometric operating scheme. They were characterized under a water velocity range from 0 to 3.68 m/s. We highlight the fact that the glass substrate device is more sensitive and less power-consuming than the silicon one under the identical operating condition, which requires further design strategies when using silicon as the substrate material. Experimental results are analyzed with respect to CFD simulations with the Finite Element Method.

This paper demonstrates a simple and low cost technology to reliably and accurately package integrated chips. Microchannels and cavities of minimum feature size of 500 μm can be reliably reproduced. In addition, the curing depth in relation to the exposure time was investigated. A simple microfluidic device, consisting of a 500 μm channel and 2 mm ports, was manufactured to demonstrate the possibilities of this technology. Extensive electrochemical experiments showed that the packaging material is a good insulator and leaves no residue on the chip.

We discuss the synthesis of zinc oxide (ZnO) and cadmium telluride (CdTe) quantum dots (QDs), the characterization of their optical properties on their own as well as combined, and their influence on the power conversion efficiency of photovoltaic structures when the QD blends were dispersed in a polymeric solution and deployed on the window surface of polycrystalline Si solar cells as down-shifting photoluminescent (PL) coatings. Upon the incorporation of increasing amounts of ZnO QDs into a colloidal solution of CdTe, the characteristic CdTe PL peak location was monotonically red-shifted from 598 nm to 611 nm. A 1:3 volumetric combination CdTe:ZnO QDs exhibited a the power conversion efficiency increase from 14.71% for an uncoated solar cell to 15.02% with the QD layer, that is, an approximate improvement of approximately 2%.

Microfluidic biochips are replacing the conventional biochemical analysers integrating the necessary functions onchip. We are interested in Flow-Based Microfluidic Biochips (FBMB), where a continuous flow of liquid is manipulated using integrated microvalves. Using microvalves and channels, more complex Fluidic Units (FUs) such as switches, micropumps, mixers and separators can be constructed. When running a biochemical application on a FBMB, fluid volumes are dispensed from input reservoirs and used by the FUs. Given a biochemical application and a biochip, we are interested in determining the fluid volume assignment for each operation of the application, such that the FUs volume requirements are satisfied, while over- and underflow are avoided and the total volume of fluid used is minimized. We propose an algorithm for this fluid assignment problem. Compared to previous work, our method is able to minimize the fluid consumption through optimal fluid assignment and reuse of fluid waste. Due to the algorithm's low complexity, fluid requirements can also be calculated during runtime for error recovery or statically unknown cases.

This paper presents a high-power energy-harvesting device based on a three-ports electrostatic comb-drive mechanism. A symmetric electrodes structure is used to reduce the binding electrostatic force, thereby allowing large displacement of the oscillator mass at a low acceleration. With an acceleration of 0.27 G at 125 Hz, output power of 150.3 μW was obtained, where mechanical stroke of over 209 μm was confirmed by using a high-speed camera.

We report the synthesis and characterization of cadmium-telluride (CdTe) quantum dots (QDs) and their performance at Terahertz frequencies employing THz time-domain spectroscopy (THZ-TDS). The data was analyzed using a combination of Fast Fourier Transform (FFT) and effective medium theory to obtain the optical characteristics of the aforementioned CdTe QDs. Additionally, we performed similar measurements while exposing the QDs to a UV excitation with a wavelength of 302 nm and observed a noticeable variation in both the real and imaginary components in the index of refraction that could prove crucial in the demonstration of reconfigurable devices operating in the THz regime.

Fluorescence thermography[1] uses the property of fluorescent dyes to lower their fluorescence emission intensity with the temperature. By using a diblock molecule, Poly-L-Lysine grafted with Fluorescein isothiocyanate (FITC), it is possible to coat a surface with a thin layer of fluorescent dye and to use temperature variations of the fluorophore to measure a temperature map at small scale on a dry surface. By using Indium Tin Oxide as transparent conductor, we can observe with this non-perturbative technique the temperature increase inside a micro dissipator.
