Distributed sensor networks operating through wireless communication offer a powerful means to sense, analyze and respond to dynamic environments spread over vast areas. Latest developments in micro electro mechanical sensors (MEMS) and related devices offer several technical and operational advantages making distributed sensor networks as a viable approach. Robustly packaged, inexpensive, ener...

Resource utilization requires a substantial consideration for a trust and reputation model to be deployed within a wireless sensor network (WSN). In the evaluation, our attention is focused on the effect of hops coefficient factor estimation on WSN with bio-inspired trust and reputation model (BTRM). We present the state-of-the-art system level evaluation of accuracy and path length of sensor n...

Recently, research works on the bio-engineering actively carried out, and the useful tool for the micromanipulation is also developed. Purpose of this research is to develop the minute size knife for the cutting of the minute object such as the cell. In this paper, we report on the microknife that cuts o the object by using ultrasonic vibration of the sharp needle. We employed the multilayer pi...

We present a vision and preliminary results for a combined RF-Biological Systems where the Electro-Magnetic energy of RF signals is transduced into control-signals for biological signaling-processes. We show how such systems can be used to build extremely low-power sensor networks. We present our approach and propose a system architecture constituted of a passive RF Front End (RF-FE), Bio-Mecha...

Novel telluride glasses with high electrical conductivity, wide infrared transparency and good resistance to crystallization are used to design an opto-electrophoretic sensor for detection and identification of hazardous microorganisms. The sensor is based on an attenuated total reflectance element made of Ge-As-Te glass that serves as both an optical sensing zone and an electrode for driving t...

This paper is intended as an investigation of new environment for interactive multimedia art with biological sensors and biological feedback. The key concept is "listen to, watch and control/interact the physiological performance". I have developed two styles of sensors for performance with bio-sensor technology and microelectronics: (1) 16-channel electromyogram sensors detecting live performa...

This paper describes the development of the sensor interface and driver program for a point of care (POC) device. The proposed POC device comprises an ARM9 embedded processor and eightchannel sensor input to measure various bio-signals. It features a user-friendly interface using a fullcolor TFT-LCD and touch-screen, and a bluetooth wireless communication module. The proposed device is based on...

Bio-inspired communication methodologies promise to enable more scalable self-organizing network infrastructures. Especially in the area of mobile ad hoc sensor networks, such solutions are required in order to qualify them for simplified development and deployment based on autonomously evolving mechanisms to work on global tasks, i.e. to show an emergent behavior. In this paper, we introduce t...

A novel approach for multicomponent patterning metal/metal oxide nanoparticles on graphene was developed, which involves region-specific plasma treatment, followed by region-selective substrate-enhanced electroless deposition of Au nanoparticles and solution alkalization of ferrous chloride tetrahydrate in the presence of ammonia into Fe3O4 nanoparticles. The resultant Fe3O4/Au multicomponent m...

Biomaterials are low cost,easily transportable and biodegradable with time.Few exampls are cellulose,chitoson and gelatin. Here we used cellulose as a base material for designing box type sensor using Comsol Tool for the detection of bio-analytes such as engine oil,ethnal,gasoline and mercury.Results shown that differential deflection and resonant frequency as found among tested analytes.Highes...
