Despite imaging techniques such as tomography and synthetic aperture having been developed more than three decades ago, they have not been fully exploited within the robotics community for gathering cross-section information of indoor environments. In this paper we propose a methodology for incorporating these concepts in multi-robot applications taking advantage of some recent developments in UWB technology.

Distributed environmental monitoring with wireless sensor networks (WSNs) is one of the most challenging research activities faced by the embedded system community in the last decade. Here, the need for pervasive, reliable and accurate monitoring systems has pushed the research towards the realization of credible deployments able to survive in harsh environments for long time. Design an effective WSN requires a good piece of engineer work, not to mention the research contribution needed to provide a credible deployment. As a matter of fact, to solve our application, we are looking for a monitoring framework scalable, adaptive with respect to topological changes in the network, power-aware in its middleware components and endowed with energy harvesting mechanisms to grant a long lifetime for the network. The paper addresses all main aspects related to the design of a WSN ranging from the -possible- need of an ad-hoc embedded system, to sensing, local and remote transmission, data storage and visualization; particular attention will be devoted to energy harvesting and management aspects at the unit and network level. Two applications, namely monitoring the marine environment and forecasting the collapse of rock faces in mountaineering areas will be the experimental leitmotiv of the presentation.

The compliance and stiffness of artery are closely related to the disease of arteries. Pulse wave velocity (PWV) in the blood vessel is a basic and common parameter in the hemodynamic. Blood pressure (BP) and blood flow wave traveling in arteries are important because the PWV is affected directly by the condition of blood vessels. However, there is no standardized method to measure the PWV and it is difficult to measure. The conventional PWV measurement uses manual calculation of the pulse wave transmission time between coronary arterial proximal and distal points on a strip chart on which the pulse wave and ECG signal are recorded. In this study, a pressure sensor consisting of strain gauges is used to measure the BP of arteries in invasive method and regular ECG electrodes are used to record the ECG signal. The R-peak point of ECG is extracted by using a reference level and time windowing technique and the ascending starting point of BP is determined by using differentiation of the BP signal and time windowing technique. The algorithm proposed in this study, which can measure PWV automatically, shows robust and good results in the extraction of feature points and calculation of PWV.

In recent years, MEMS gyroscope which is a kind of angular-rate-sensor has been improved greatly. In this paper, the effect of temperature changing on MEMS gyroscope is analysed. An evaluation and compensation platform based on the MCU and PC software has been fabricated. The temperature tests were done and some novel compensation algorithms were presented to fit the temperature curve. The thermal bias drift of the gyroscope compensated by the platform was reduced to 0.0667deg/s/degC compared with 0.618deg/s/degC before compensation.

Thick films of AR grade ZnO were prepared by screen-printing technique. The gas sensing performance of thick films were tested for various gases. It showed maximum sensitivity to CO gas at 100degC for 100 ppm gas concentration. To improve the sensitivity and selectivity of the film towards a particular gas, ZnO thick films were surface modified by dipping them in a solution of nano silver for different intervals of time. These surface modified ZnO films showed larger sensitivity to H2S gas (100 ppm) than pure ZnO film at 300degC. Nano silver on the surface of the film shifts the reactivity of film from CO to H2S gas. A systematic study, of sensing performance of the sensor, indicates the key role-played by the nano silver species on the surface. The sensitivity, selectivity, response and recovery time of the sensor were measured and presented.

The taste sensor was widely used in distinguishing various taste substances. However, the taste sensor has poorer sensitivity to uncharged molecules such as caffeine, a bitter substance, than to charged taste substances. In the present study, we discussed the sensitivity of caffeine detection using a taste sensor with lipid/polymer membranes that were formed with different length of methyl group of lipid, namely, tetra-n-ctylammonium bromide (R8), tetrakis-(decyl)-ammonium bromide (R10), tetradodecylammonium bromide (TDAB; R12), and tetrahexadecylammonium bromide (R16). As a result, we observed that the electric responses of the lipid membranes to caffeine were associated with the length of alkyl chain of a lipid and an optimum concentration of the lipids in membranes was also observed to enhance the sensitivity of caffeine with taste sensor.

This paper describes the scaling effect on the micro-machined gas-pendulum dual-axis tilt sensor from two aspects, microscale gas flow and microsystem technology, based on the design, fabrication and capability of the sensor; detailedly founds the theory model and analysis method of the sensor miniaturization in every stage whose demarcation points are 0.25 mum and 0.5 mum; simulates the gas flow in the continuous medium hypothesis. This paper analyses the effect of surface-area-to-volume ratio increase, surface roughness, viscous force etc on the gas flow of the micro sensor. This paper computes tests and experiments the residual stress of the electrodes and multilayer films of this sensor, puts forward the method to eliminate residual stress, solves the problem that films break off in the process of chip fabrication. The harvest of this paper is very important to farther micromation and improving capability of micro-machined gas-pendulum dual-axis tilt sensors.

Suspended-gate FETs, namely SGFET, with sub-micron gap are used to detect electrically transferrin concentration directly without any labelling. The fabrication of the device and the process to functionnalize it, so that it will be able to detect transferrin, are given. The feasibility of the detection is demonstrated and a range of detectable concentrations is determined. Concentration, as low as 100 ng/mL, is measured. The maximum concentration in the linear regime, 5 mug/mL, is under the range of the standard clinical techniques. The fabrication of the device is compatible with usual microelectronic tools. Its functionalization can be easily implemented in any chemical environment. Present results open the way to simultaneous detection of many proteins giving in real time indication on complicated biologic functions as liver metabolism.

During hyperthermia therapy for cancer treatment magnetic fluid is injected into the tumor. Hyperthermia therapy exploits the fact that cancer cells are more sensitive to heat than healthy cells. Generally all parameters except the magnetic fluid weight density are known in the specific heat equation which governs the heat given in hyperthermia therapy to destroy cancer cells. Hence, accurate estimation of magnetic fluid weight density inside the body is critical for successful treatment. A unique needle-type GMR sensor is fabricated for inserting into the body in a low-invasive way. This paper presents analytical analysis and experimental results obtained by estimating magnetic fluid weight density in large cavities by the fabricated needle-type GMR sensor.

This paper is focused on two fusion estimation algorithms weighted by matrices and scalars. Relationship between them is theoretically established. We present two fast algorithms addressing computation of matrix weights that arise in multidimensional estimation problems. The first algorithm is based on the Cholesky factorization. And since determination of the optimal matrix weights in real-time applications is not practical, we propose the second algorithm based on approximate calculations using special approximation for cross-covariances. Analysis of computational complexity of the both fast fusion algorithms is proposed. Examples demonstrating low-computational complexity of the fast fusion algorithms are given.
