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...
This paper presents a reduced order model including the resonator and the mechanical moment induced by the thin film on the resonator. The model development is presented as well as its experimental validation with four magnetometer prototypes. This model is then used to investigate the optimization of the thin film position on the resonator as well as the advantages of various shapes of resonators.
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,...
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...
Thermal Ultraviolet NanoImprint Lithography is a fast and reliable process to manufacture large scale integrated polymer-based optical components from a soft stamp. This technology already provides polymer integrated components for optical communications operating in the infrared region. However, several fabrication issues must be addressed to enable reliable mass production of optical components...
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...
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...
An aluminum-nitride (AlN) based energy-harvesting MEMS sensor is developed. We aimed at realizing energy-harvesting sensor with functional feature of wide-band response at low-frequency vibration domain, owing to the high-power density of vibration sources energy in a particular low frequency with several Hz deviations. By simplifying and analyzing the vibration module of the sensor structure, a special...
This paper presents a low-cost and high-precision pH sensor using silicon nanowire (SiNW) array. With the help of traditional microfabrication technology, low-cost as well as highly controllable SiNW array was fabricated. After functionalized with APTES solution, SiNW array shows rapid and reliable response to pH value. With excellent linearity and repeatability, accuracy of the sensor can be achieved...
This paper reports a novel thin film based flexible clamp-on type current sensor with 250 turns micropatterned Cu coil (line / space = 50 μm / 105 μm) formed by through-holes and flexible printed circuits (FPC) technologies for wireless sensor networks. Using flexible electronics techniques, microvias and fine stripe Cu patterns could be formed around 60-mm-long and 14.5-mm-wide permalloy film sandwiched...
This paper presents the design, FEM modeling and experimental characterization of the elastic-plastic behavior of electroplated gold specimens undergoing tensile loading. The test structures are designed and optimized to achieve high stress values in the double-clamped specimen with a rectangular cross-section in the middle of the test structure. High stresses in the specimen are achieved by using...
Since the beginning of the in situ exploration of alien worlds in the solar system, the characterization of the chemical composition in volatile materials and organic molecules is among the top priorities. Indeed, these compounds learn us about the origin and history of these world, their potential for habitability, and somehow the nature of resources they could provide, especially for future inhabited...
A MEMS-based gas chromatograph (GC) front-end for a mass spectrometer has been developed for space applications. The GC uses Molecular Vapor Deposition (MVD) to achieve a uniform coating of the GC column. Particular attention has been paid to the fluidic connections of the MEMS to the external tubing.
