A team consisting of Teledyne Scientific Company, the University of California at Santa Barbara (UCSB) and the Army Research Laboratory (ARL) is developing technologies in support of automated data exfiltration from heterogeneous battlefield sensor networks as part of a US Army contract with the Institute for Collaborative Biotechnologies (ICB) at UCSB. The objective of the program is to design...

Wireless sensor networks (WSNs) have emerged in strategic applications such as target detection, localization, and tracking in battlefields, where the large-scale nature renders centralized control prohibitive. In addition, the finite batteries in sensor nodes demand energy-aware network control. In this paper, we propose an energy-efficient topology management model that allows clustered nodes...

A quality literature survey was carried out in the area of Wireless Sensor Network and it was observed that leach protocol which has been proposed in the literature phase continued some problem, i.e. cluster construction and cluster head selection. PEGASIS overcome shortcomings of LEACH but PEGASIS still lack in outperforms the other two protocols in terms of system lifetime and quality of netw...

A novel single silicon thin film field-effect-transistor (FET) is developed for use as a sensor to monitor transport and chemical properties of liquids in microfluidic systems. The sensor elements which are compatible with existing (bio-)chemical sensor schemes based on ion-sensitive-field-effect-transistors (ISFET) can detect capillary filling speed and level in aqueous solutions. Using a tran...

Wireless sensor network (WSN) is a network of independent nodes used for environment monitoring. At the same time WSN developers face challenges that come from failure of communication link due to limited energy. We need to integrate zero wastage and minimum energy consumption technology. As MAC protocol is more energy efficient protocol as compare to others Thus in this paper we use MAC protoc...

This paper presents a micro-biosensor based on Electrical Bio-Impedance Spectroscopy (EBIS), applied to blood cells characterization and diagnosis. This sensor uses microfluidic flow, coupled to EBIS system to perform cell by cell measurements at high flow rate, up to several hundred cells per second. Two devices were realized with different materials, SU_8 resin and polydimethylsyloxane PDMS t...

BACKGROUND Human life can be further improved if diseases and disorders can be predicted before they become dangerous, by correctly recognizing signals from the human body, so in order to make disease detection more precise, various body-signals need to be measured simultaneously in a synchronized manner. OBJECT This research aims at developing an integrated system for measuring four signals ...

Wireless Sensor Networks (WSN) are emerging as a new tier within the IT scheme and a rich domain of active analysis involving hardware and system design, networking, and programming models, data management, security and social actors. Wireless sensor networks are compared with wired networks are additional well vulnerable to attacks and intrusions. The intrusion detection is outlined as a mecha...

In this paper, we propose a silicon-retina-based stereo vision system, used for pre-crash warning or rather side-impact detection applications in vehicles. The bio-inspired silicon retina sensor is a new kind of sensor, which delivers data asynchronously and only if the intensity of the ambient light changes. Therefore, the amount of data that must be processed decreases significantly compared ...

The emergence of personalized and stratified medicine requires label-free, low-cost diagnostic technology capable of monitoring multiple disease biomarkers in parallel. Silicon photonic biosensors combine high-sensitivity analysis with scalable, low-cost manufacturing, but they tend to measure only a single biomarker and provide no information about their (bio)chemical activity. Here we introdu...
