Only in recent years, the challenge of ubiquitous sensing environments has become a technical possibility with growing research in wireless sensing networks. As the field of mobile computing and communication advances, so does the idea of a distributed, ad-hoc wireless network of hundreds to thousands of microsensors, which can be randomly scattered in the area of interest. A wireless communica...

Microsensors are miniaturized analytical devices for making in-situ chemical measurements in biological systems with extraordinary temporal resolution. Their most severe limitation is chemical selectivity. Here, we suggest guidelines that can be applied to a range of in-vivo microsensor applications for evaluation of analyte identification and improvement of selectivity. # 2003 Published by Els...

A novel fabrication method for stretchable magnetoresistive sensors is introduced, which allows the transfer of a complex microsensor systems prepared on common rigid donor substrates to prestretched elastomeric membranes in a single step. This direct transfer printing method boosts the fabrication potential of stretchable magnetoelectronics in terms of miniaturization and level of complexity, ...

We used a novel amperometric microsensor for measuring hydrogen gas production and consumption at high spatio-temporal resolution in cyanobacterial biofilms and mats dominated by non-heterocystous filamentous cyanobacteria (Microcoleus chtonoplastes and Oscillatoria sp.). The new microsensor is based on the use of an organic electrolyte and a stable internal reference system and can be equipped...

New technology is changing the nature of sensors and the way they interface with data acquisition and control systems. Researchers at U.C. Berkeley have developed an open-source hardware and software platform that combines sensing, communications, and computing into a complete architecture. The first commercial generation of this platform was dubbed the Rene Mote, and several thousand of these ...

Chemical field effect transistors (ChemFETs) have been fabricated and adapted to the ammonium ion detection thanks to polysiloxane ionosensitive layers. The chip design and packaging process have been optimized to be adapted to a specific flow head measurement system. Experimental results evidence quasinernstian response for the pNH4 measurement. This microsensor will be used for water analysis...
