Temperature, pressure and relative humidity, in the space surrounding the drop, are recorded, using a portable sensor (Omega Engineering, Inc. iBTHX-W), and reflector height computed and adjusted as previously described.
These results are of significant potential valuable in the field of soil ecosystem observation, specifically for sensor selection and future portable sensor design.
This work responds to this challenge by designing, fabricating, and evaluating a portable sensor strip for naked-eye chromatic assaying of trace amount of Pb2+.
In summary, by combining synthetic receptors with thermal measurement techniques it is possible to develop a portable sensor platform that is capable of low-cost and straightforward detection of biomolecules.
Fifteen Singaporean subjects participated in a 7-day longitudinal experiment in which they carried a portable sensor that continuously recorded personal air temperature, relative humidity and carbon dioxide concentration at 1-min intervals.
Gang Peng of the Israel Institute of Technology in Haifa and colleagues have now developed what they say is an inexpensive, portable sensor technology that can quickly distinguish between the breath of lung cancer patients and healthy people.
The results have demonstrated the potential of the sensor arrays coupled with pattern recognition for the detection of acetone in diabetic breath, which upon further refinements and testing could lead to a useful portable sensor device for human breath recognition.
Now in her third year, she's working to develop a portable sensor that would allow patients with congestive heart failure to quickly and noninvasively assess their hydration state and better manage their disease. .
The remarkable advantages (miniaturization and low-cost) fill the bill of point-care diagnostics for portable sensor development.
