In this paper, a new design of a sensor for conductivity measurements is presented. Impedance spectroscopy is often used as experimental techniques to detect and measure changes in electrical conductivity using an equivalent circuit model which is adapted to the electrode geometries used. This theoretical study allows us to determine the geometric factor of an interdigital electrode sensor. While the simulation performed on COMSOL allows us to validate the measurement frequency range as well as the equivalent circuit model which include the double layer capacitance phenomena.

This work report PVDF micro machining process by RIE without much loss of its piezoelectric constant. L/S (70/130_μm) of fine structure was realized in this work with high etch rate. O2 mixing feed gases of CF4, CHF3, SF6 and 100 % of O2 were used. At the condition of 100% O2 gas plasma and at a higher of RF power, the better of surface state and higher of aspect ratio structure could be realized.

With prolific usage of vibration analysis to extract information about different structures (buildings and bridges etc.), vibration sensors have become an important device in Structural Health Monitoring (SHM). In this paper, we target geophone which is a commonly used sensor in SHM. Each geophone is unique with regard to application, sensitivity, and electrical characteristics. For the geophone that has been used in this study, we focused on the low frequency response to develop an optimum conditioning circuit for the sensor. Geophone response compensator is essential for conditioning vibration signals at very low frequencies. In this article, we have presented two different techniques to reconstruct the low frequency response characteristics of the geophone. Several analog electronic circuits to establish the feasibility of the suggested techniques for vibration signal conditioning by the geophone on hand are presented in this article.

A major cause of cancer-associated mortality is metastasis. During metastasis cancer cells use the circulatory system to migrate and form secondary tumours in distant organs. Cancer cells which enter the peripheral circulation (circulating tumour cells) are of paramount research and clinical interest as they can be used as a biomarker of cancer progression and survival. Tumour cells produce more lactic acid than their normal counterparts. This paper reports on novel approach of using low power athermal electromagnetic waves as a sensing mechanism for early cancer detection.

In this paper, we describe the relationship between the presence or absence of interest and the fixation time of face orientation. There is a conventional method of measuring the fixation time of line-of-sight orientation to prevent accidents due to carelessness. In addition, studies are being performed on the estimation of the relationship between face orientation and line-of-sight orientation. However, even if face and line-of-sight remain, it has not been confirmed whether people are interested. Therefore, we conducted experiments to investigate the relationship between the presence or absence of interest and the fixation time of face orientation. We simultaneously measured the change in interest and face orientation with time as subjects watched two movies. As a result, it was suggested that face orientation remained longer for an object of interest.

Catalytic combustion hydrogen gas sensors using quartz resonators have been developed to detect hydrogen gas leakage. In order to improve stability of its sensitivity, Au thin film was studied as a non-catalysis heater material. Around 50 Ω Au heaters, which is relatively low resistance value, were designed to be driven with single-supply op-amp. As a result of evaluating using the prototype sensor, the heaters with linear TCR same great as a Pt thin film were obtained. By controlling the temperature with the analog circuit, hydrogen sensitivity with high linearity was confirmed. As result, the effectiveness of the Au thin film heater was demonstrated.

A novel noncontact method to measure both surface and internal temperatures of a heated cylindrical rod end is proposed. In the method a laser ultrasonic technique providing noncontact measurements of ultrasonic waves in such heated rod is employed. To quantitatively determine both the surface and internal temperatures near the rod end, an effective ultrasonic thermometry has been developed by considering the propagation direction and path of the ultrasonic waves in the rod generated by pulsed-laser irradiation. The thermometry is basically a combined method consisting of ultrasonic wave velocities measurements based on pitch-catch configurations and a one-dimensional finite difference calculation for unsteady heat conduction. The advantage of the method is that there is no need to know the thermal boundary condition at the heating surface where the thermal state is often unstable and unknown. To demonstrate the feasibility of the proposed method, experiments with an aluminum rod whose end surface is heated by a gas burner are carried out. A laser ultrasonic system consisting of a pulsed laser generator (Nd:YAG, 1064 nm, 180 mJ) and a laser Doppler vibrometer (He-Ne, 633 nm, <1mW) is used for noncontact measurements of shear and longitudinal waves propagating in the aluminum rod during heating. It has been shown that the ultrasonically determined temperature distributions almost agree with those measured by thermocouples.

Precision agriculture has been implemented in various cultivation operations for various crops. Recently, autonomous mower tractor with variable rate fertilization has been tried. Variable rate fertilization requires quantification of grass growth level. Objective of this study was to compare the performance of potential sensors under different growth levels and sensor operation conditions. A CCD camera, an ultrasonic module, and an optical reflectance sensor (i.e., Crop Circle) were tested at fields with different grass growth levels. Effects of sensor mounting height and angle were investigated. Effects of vehicle (i.e., mower tractor) vibration and traveling were also investigated: under static, vibration and no traveling, and vibration with traveling conditions. Results showed that sensor mounting height had a little effect on the sensor performance, and grass growth level was successfully quantified. Camera angle of 90 ° showed the best performance with less noise. The ultrasonic sensor could work with less deviation on static condition, whereas, CCD camera proved the applicability in all operating conditions. Optical reflectance sensor showed a little effect on the grass growth detection results. This study would provide information useful for automated grass growth mapping and variable fertilization recommendation.

The Internet of Things (IoT) with a direct internet connectivity for global access is one of the promising technologies for future communication systems. The Internet Protocol version 6 (IPv6) based routing protocols that are currently available for IoT are prone to various vulnerabilities. Hence, the Personally Identifiable Information (PII) stored and/or communicated in IoT can easily be compromised. In this paper, we propose a Bio-inspired Secure IPv6 Communication Protocol (BSCoP) for IoT. We have enhanced the IPv6 Routing Protocol for Low-Power and Lossy Networks (RFC 6550) by incorporating a classification algorithm inspired by the Artificial Immune System (AIS). The AIS-based algorithm works by detecting the routing behavior of the communicating nodes in the local routing tables and classify the misbehaving nodes as non-self. With the help of the classification algorithm, we can detect excessive broadcasts and isolate them to improve power and transmission rates of the transmitted packets in a cluster of IoT nodes. The detailed experimental results show the promising performance of the proposed protocol while offering the security desired in cyberspace in terms of energy consumption and data packet rate.

A very wide band (from 900 MHz to 12 GHz), enhancing beam capacity patch antennae system is developed in FR4 substrate with a dielectric constant 4.4 and 1.2 mm of height for vital detection purposes. This work focuses on development of 3D-orthogonal patch antennae to detect the respiratory beat at different frequencies. A transceiver antennae is proposed that allows to detect the thorax displacement at four band of frequencies, from L band to X band. The measurement shows that the proposed antennae can operate in extra wide band frequency to detect the vital signs.
