In this paper presents two microsensors structures compatible with microelectronic technologies that are analyzed for application in radiometers. The first structure is formed by one resistor that is made by doping a monocrystalline silicon substrate with boron. The second is a polysilicon resistor doped with phosphorous, over a silicon dioxide (SiO2). The analysis is made by mathematical model...

The electrochemical determination of nitric oxide in seawater with microelectrodes is reported in this paper. Two electrodes, ISO-NOPMC microsensor and modified platinum microelectrode, are evaluated for their performance in seawater. The peak current is found to be linear with the NO concentration in the range 1×10-1.2×10 mol/l for both microelectrodes. The detection limit of ISO-NOPMC microse...

Wireless distributed microsensor systems will enable fault tolerant monitoring and control of a variety of applications. Due to the large number of microsensor nodes that may be deployed and the long required system lifetimes, replacing the battery is not an option. Sensor systems must utilize the minimal possible energy while operating over a wide range of operating scenarios. This paper prese...

A novel dopamine targeted electrochemical detection strategy has enabled the phenotyping and non-invasive monitoring of human midbrain organoids (healthy Parkinson's diseased), by employing a redox-cycling based microsensor.

We provide a broad review of approaches for developing chemosensor systems whose operating parameters can adapt in response to environmental changes or application needs. Adaptation may take place at the instrumentation level (e.g., tunable sensors) and at the data-analysis level (e.g., adaptive classifiers). We discuss several strategies that provide tunability at the device level: modulation ...
