Zinc oxide pressure sensor.(SENSORS)
Advanced Ceramics Report, June, 2007
Zinc oxide nanowires that respond electrically when bent could be used to measure minute forces and pressures say researchers at Georgia Institute of Technology, USA, who have developed tiny devices that can measure extremely small forces, in the nano- to piconewton range.
According to Dr Zhong Lin Wang who led the research, the ability to measure such small forces could lead to implantable devices that could continuously measure minute blood-pressure changes. The sensors could also be installed on the wings of airplanes and spacecraft to monitor small pressure fluctuations. Also, because the flow of current through the nanowire responds quickly, it could be used to make a sensitive trigger for car air bags. "If it's subject to an external force, then it turns...
