Different 2D materials for microfluidic sensors and their possible use in various health care environmental applications including wearable are critically addressed.

The research areas of mobile robotic sensors lie in the intersection of two major fields of investigations carried out by quite distinct communities of researchers: autonomous robots and mobile sensor networks. Robotic sensors are micro-robots capable of locomotion and sensing. Like the sensors in wireless sensor networks, they are myopic: their sensing range is limited. Unlike the sensors in w...

We consider the problem of uniformly dispersing mobile robotic sensors in a simply connected orthogonal space of unknown shape. The mobile sensors are injected into the space from one or more entry points and rely only on sensed local information within a restricted radius. Unlike the existing solution, we allow the sensors to be asynchronous and show how, even in this case, the sensors can uni...

This paper gives first of all the definition of the work function of an electronic as well as an ionic conductor. FET-type gas sensors known from the literature are considered in view of this basic theory and the parameter of the work function which is responsible for the sensing properties is noticed. This appears not always to be possible for the various types of gas sensors, in this case the...

Presented in this report is an overview of robotic sensors, many of which are in experimental stages. Two main sensor types are discussed: contact and noncontact. Descriptions of the physical measurements. how they are measured, and operating principles of specific devices are provided for both types of sensors. Contact, or tactile, sensors comprise three groups: touch, proximity, and slip sens...

The goal of this project is to design and build a cost-effective oxygen sensor through the use of fluorescence spectroscopic analysis on the Tris(2,2’bipyridal)dichlororuthenium(II) compound and low-cost support electronics. The objective of the project is to generate a Stern-Volmer chart and demonstrate the oxygen-quenching effect on fluorescent intensity and lifetime. A customized P-I-N photo...

pollutions. Recently, both Persian Gulf and Gulf of Oman are experiencing several types of pollution including oil spills and heavy metal pollutions as well as Harmful Algal Bloom (HAB) caused by biological and environmental changes. Theiroccurrence of the red tide or harmful algal bloom during fall and winter 2008-2009 caused numerous unknown factors in the Strait of Hormuz, Persian Gulf and G...

Surface plasmon resonance (SPR) imaging sensors realize label free, real-time, highly sensitive, quantitative, high throughput biological interaction monitoring and the binding profiles from multi-analytes further provide the binding kinetic parameters between different bio-molecules. In the past two decades, SPR imaging sensors found rapid increasing applications in fundamental biological stud...
