NEMS Mass Sensor by Focused Ion Beam Fabrication

Boonliang B., Prewett P.D., Ward M.C.L., Docker P.T., Birmingham University, UK

Due to rising industrial demands (food, biology, control), there is a drive to develop smaller, more sensitive sensor-devices with real-time capability. The objective of this work is to utilise Focused Ion Beam (FIB) fabrication technology [...]

Frequency Stability and Noise Characteristics of Ultra-High Frequency (UHF) Nanoelectromechanical Resonators

Feng X.L., Roukes M.L., California Institute of Technology, US

Nanoelectromechanical systems (NEMS) are emerging as great candidates for a variety of technological applications ranging from sensors and actuators to signal processing and communications [1]. Nanofabricated high-frequency (often in the VHF/UHF bands) electromechanical resonators (i.e., [...]

A Generic Sensor for Ultra Low Analyte Concentration Detection

Hedley J., McNeil C.J., Burdess J.S., Harris A.J., Dobson M.G., Suarez G., Berney H., Newcastle University, UK

This paper reports on the development of a MEMS based generic mass sensor system (international patents pending) aimed at quantitative analyte measurement with a sensitivity of the order of 0.01 ng per cm sq. The [...]
