The world had faced a leap in the field of science and technology to a great extent in the last five decades. The fabrication of materials is done in a more miniaturized way for merging the different aspects of the working field in a single device. The paper presents a review of different technologies that had been used electronically for the last two decades for the production of substances that are used in the field of electronics, electrical and biochemistry. The review includes the development of nanoparticles, biosensors and other small scaled devices for practical applications like detection of bacteria and other pathogens. The paper also describes the process of ink-jet printing that had been used since its introduction and gives a few methods for making stable conductive compounds like silver, copper in room temperature.

In this paper, the multi-point hydrogen detection system has been presented using the hetero-core optical fiber hydrogen tip sensor based on surface plasmon resonance (SPR) and time domain interrogating system based on Pseudorandom Noise code correlation reflectometry (PNCR) This method makes use of the correlation between a launched pseudorandom noise code signal and its reflection, can obtain a high signal to noise ration. A hetero-core optical fiber SPR hydrogen tip sensor consists of multilayer films of 25 nm Au/60 nm Ta2O5/5 nm Pd, coated onto a cylindrical cladding surface. The SPR resonant wavelength is shifted 17 nm for 4% hydrogen concentration in nitrogen. In addition, multi-point hydrogen detection is demonstrated using two SPR hydrogen tip sensors. All sensors have successfully detected the hydrogen concentration with real-time responses and sufficient sensitivities.

Multispectral imaging has been studied in recent years as a means of assessing fruit firmness. Here we report on the development of a static multispectral imaging system (MSI) that was used to validate the potential of the technique for high-speed commercial grading. The system consists of a high-performance CMOS camera, four lasers, electronically controlled shutters and a location control system. It captures four spectral scattering images on the fruit. In this study 100 `Royal Gala' apples have been measured using the static MSI. The MSI measurements were applied on the intact apple and also on a flat surface of internal flesh exposed by removing a thick skin slice. The scattering profiles were fitted with a standard light diffusion model and a heuristic modified Lorentzian model. The results showed that the correlations between penetrometer firmness and model parameters were poor, with the correlation coefficient, R, ranging from 0.4 to 0.8 in the best circumstance of the flat surface measurements. Although multivariate models can improve the correlations, this work suggests that laser scattering information on its own is not sufficient to predict the firmness.

Presented research reports on an improved method and enhanced limits of detection for phthalates; a hazardous additive used in the production of plastics by solid-phase micro-extraction (SPME) polymer in comparison to molecularly imprinted solid-phase extraction (MISPE) polymer. The polymers were functionalized on an interdigital capacitive sensor for selective binding of phthalate molecules from a complex mixture of chemicals. Both polymers owned predetermined selectivity by formation of valuable molecular recognition sites for Bis (2-ethylhexyl) phthalate (DEHP). Polymers were immobilized on planar electrochemical sensor fabricated on a single crystal silicon substrate with 500 nm sputtered gold electrodes fabricated using MEMS fabrication techniques. Impedance spectra were obtained using electrochemical impedance spectroscopy (EIS) to determine sample conductance for evaluation of phthalate concentration in the spiked sample solutions with various phthalate concentrations. Experimental results revealed that the ability of SPME polymer to adsorb target molecules on the sensing surface is better than that of MISPE polymer for phthalates in the sensing system. Testing the extracted samples using high performance liquid chromatography with photodiode array detectors validated the results.

Spoken keyword recognition has been under the spotlight for the past several decades, but has gained significant attention in recent years due to the rapid increase in front-end technology applications for mobile and wearable computing. This work presents the trade-off in performance between Artificial Neural Networks (ANN) and Dynamic Time Warping (DTW) methodologies, implemented for this task under three different transient noise conditions (inside a car, in a pub, and outdoors), where no external noise reduction pre-processing is used. For this purpose, two types of recognition models were implemented: speaker dependent (SD) and speaker independent (SI). Experimental results show comparable high keyword recognition precision in SD models for both ANN and DTW using baseline data, i.e. no transient noise, but for the SI models, a significant drop in precision was observed for the case of DTW. Additional precision analyses present the results on how the different types of transient noise affect the recognition methodologies of interest. From the point of view of storage resources, both methodologies require comparable memory usage for the SD models, however, the SI model increases the memory needed with the DTW methodology. Lastly, time performance analysis showed a faster recognition time using the ANN methodology.

This paper introduces a self-designed wearable inertial measurement unit (IMU-BMSJv2) and the calibration of its tri-axial accelerometers. We compare two popular accelerometer calibration approaches, the classical method (attitude dependent) and auto calibration method (attitude independent). Both these two calibration methods have been applied for the calibration of the self-designed IMU-BMSJv2; verification experiments have been carried out for the calibration of the tri-axial accelerometers. Experimental results show that although the auto-calibration method has the advantage of attitude independency, the classical calibration method can achieve better parameter estimation. We thus claim that the attitude dependent calibration method is still the first option considered when certain experimental conditions are satisfied.

An innovative process is proposed for the calibration of thermometric devices, combining materials which change state at primary temperature calibration points defined in international standards, and electrical impedance measurement techniques. The process will use pure samples of such materials and a measurement apparatus which enables the automated matching of the elimination of measurement bias to each of a number of calibration points, improving resolution and accuracy. The proposed process will be low-cost to allow implementation and regular calibration of temperature sensing and controlled devices in a standard manufacturing process.

This research develops a honeybee behavior monitoring system. The proposed system monitors honeybees' daily activities of getting in and coming out their beehive. It provides a new way to observe honeybee behavior and replace the methods of human observation. Specifically, it automatically records environmental parameters near and in the beehive. The information collected by the system is used for statistical analysis, and the analyzed results help researchers have a better understanding of the relationship between the environmental factors and honeybees' activities of getting in and coming out of their beehive. The research results show that the proposed system is beneficial to future research projects involving large scale monitoring of bee colony activities.

In this work, an interesting Pd/GaN Schottky diode-type hydrogen sensor, prepared by electrophoretic deposition (EPD) method, is fabricated and investigated. The studied device shows a high sensing response of 6.67×104 when exposing to a 1% H2/air gas at 100°C, and also detect even as low as 50 ppm H2/air gas. Moreover the studied device shows short response time and recovery time as 10 and 82 s, respectively, when exposing to a 1% H2/air gas at 150°C. Based on these excellent properties, the studied device gives a promise for high-performance hydrogen sensing applications.
