Passive Downhole Pressure Sensor Based on Surface Acoustic Wave Technology

A passive surface acoustic wave (SAW) pressure sensor was developed for real-time pressure monitoring in downhole application. The passive pressure sensor consists of a SAW resonator, which is attached to a circular metal diaphragm used as a pressure transducer. While the membrane deflects as a function of pressure applied, the frequency response changes due to the variation of the SAW propagat...

Scanning the Issue Special Issue on Sensor Networks and Applications

Microsensor network technology will have a significant impact on our lives in the 21st century. Microsensor devices, ranging in size from cubic inches to cubic millimeters, will each have multiple on board miniaturized sensors (such as for light, temperature, humidity, acoustics, imaging, etc.), with considerable processing power, in each geographic position ability through global positioning s...

Special issue on atomically controlled fabrication technology

Editorial The Global Center of Excellence (GCOE) for atomically controlled fabrication technology was established in 2008 by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT), as a succession program of the 21st Century COE program for atomistic fabrication technology promoted from 2003 to 2007. The GCOE program is implemented by three departments, namely the De...
