This paper presents a unique technique for noninvasive estimation of blood glucose concentration using near infra red spectroscopy. The spectroscopy has been performed at the second overtone of glucose which falls in the near infra red region. The near infra red spectroscopy has been performed using transmission photoplethsymography (PPG). The analog front end system has been implemented to get the PPG signal at the near infra red wavelengths of 1070nm, 950nm, 935nm. The PPG signal that has been obtained is processed and double regression analysis is carried out with the artificial neural network for estimating the glucose levels. The root mean square error of the prediction was 5.84mg/dL.

Microfluidic systems, which handle fluids in very small quantities, are becoming increasingly popular in biomedical applications. This research aims to develop a wireless power supply module which can drive microfluidic sensor and actuator systems using inductive power transfer (IPT) with super capacitor storage. The main challenge is to source a variety of microvalves which have different power requirements ranging from micro-watts to couple of watts. An IPT solution is proposed where the primary side is external to the microfluidic system while the secondary coil will be housed within the microvalve, which is very challenging as miniaturization is vital. Supercapacitors are used as a backup to source high power requirements of the system.

In this paper a fast and innovative three-dimensional vision system, having high resolution in the surface reconstruction, is discussed. It is based on a triangulation 3D laser scanner with a linear beam shape. The high precision (few microns) is guaranteed by very small laser line width, small camera pixel-size and proper optical properties of the Telecentric Lens. The entire system has been tested on two kinds of sample objects such as a 20 €cent coin and a set of precision drilling tools. The main purpose of this work is the detection and reconstruction of the 3D surface of tiny objects and the measurement of their surface defects with high accuracy. Furthermore the occlusion problem is faced and solved by properly handling the camera-laser setup. Experimental tests prove the high precision of the system that can reach a resolution of 15 μm.

In the last few years Electronic Noses (ENs) have been revealed to be a very effective and fast tool for monitoring the microbiological spoilage and food quality control. European regulations report the maximum concentration of mycotoxins permitted in green coffee beans. The aim of this study was to test the ability of a novel EN, equipped with an array of MOX gas sensors based on thin films as well as nanowires, to early detect mold contaminations from Aspergillus spp., in cooperation with classical microbiological and chemical techniques like Gas Chromatography coupled with Mass Spectroscopy with SPME technique. In general the selection of the green coffee is controlled by visual inspection of shape, color and size. However, this process in often not enough to prevent the entrance in the food chains of contaminated products. We have demonstrated that the novel EN is able to early detect the qualitative and quantitative differences between contaminate and uncontaminated samples. Achieved results vividly recommend the use of our EN as a quality control tool in coffee producer industry.

We are developing a method that allows remote soil moisture measurement from electromagnetic sensors that are mounted on irrigators. To do that, techniques from the impulse (ultra-wideband) radar are applied, which enables the measurement of soil reflection at resolutions smaller than the antenna beamwidths of the radar. We derive a relationship between the radar's parameter (i.e. pulse-width, antenna parameters, radar location and sensing angle with respect to ground level) and the soil surface resolution that the radar is capable of achieving. In addition, we also propose a method to calculate the radar backscatter coefficient of the ground from the signals that are received by the radar. Using the proposed method, radar measurements are performed on wet pasture to measure the radar backscatter coefficients at different grazing angles. Measured results show that radar backscatter coefficients can be reliably measured at the angles up to 60 degrees from nadir. This paper presents the progress in our ongoing work to develop a small and practical remote soil moisture measurement for smart irrigation.

This paper proposes the feasibility of using triboacoustically emitted signals (TES) generated between finger (covered or uncovered) and tracing surfaces (with or without mechanoreceptors) as an input method for mobile users. This is achieved by localizing upon the acoustic signals generated during the net motion between 2 surfaces in contact. This property allows it to be highly versatile in many real life scenarios. The design of the system opportunistically utilizes the microphone's frequency limitations to define its fundamental frequency of 25kHz and the uniqueness of each signal captured to separate the microphones pairs at the 8th subharmonic distance of separation. The system was proven to be feasible and versatile as test results show it could recreate triboacoustically traced shapes when coupled with different types of surface materials. Results show that the acoustical localization system is able to recreate shapes of a tracing event similar to that produced by the visually localized system but at lower precision and accuracy.

Different MAC techniques in body area networks (BAN) are to make different tradeoffs to suit for the variety of situations that may be caused by the heterogeneous traffic behavior of the BANs. Previously, we proposed a dynamic delayed MAC scheme with a fuzzy technique to add a traffic adaptive quality to the existing IEEE 802.15.4 which addresses traffic diversity in BAN applications. In this paper we investigate reducing the complexity of our previous method by integrating it with a caching technique enabling the MAC algorithm to minimize the iterations of running the fuzzy engine. We examine the efficiency of the previously fuzzy-based MAC algorithm in terms of energy to be implemented on real SHIMMER sensor platforms by evaluating the reliability and battery lifetime.

We have achieved pico-Tesla (10-8 Oe) resolution for micro magneto-impedance (MI) sensors by utilizing the ultra-low intrinsic noise of amorphous wire the pulse magneto-impedance effect. We previously reported a study on bio-magnetic measurement using a pico-Tesla resolution MI sensor without any magnetic shielding. In order to detect very weak magnetic fields such as bio-magnetic fields, we constructed an MI gradiometer to cancel out background uniform noise such as the geomagnetic field. In the present study, we measured brainwaves using an MI sensor, and the results showed that brain activity can be evaluated by the sensor. We compared our results with electroencephalogram (EEG) and magneto-encephalogram (MEG) data reported by previous studies, and considered the reliability of the data. The results suggest that the MI sensor is a convenient device for daily monitoring using MEG signals.

The human auditory system perceives sound in a much different manner than sound is measured by modern audio sensing systems. The most commonly referenced aspects of auditory perception are loudness and pitch which relate to the objective measures of frequency and sound pressure levels. This paper describes an efficient and accurate method for the conversion of the sensed factors of frequency and sound pressure level to perceived loudness and pitch. This method is achieved through the modeling of the auditory system using artificial neural networks and will be shown to have certain advantages over previous methods.
