Utilization of carbon nanofibers for airborne ultrasonic acoustic field detection using heterodyne interferometry.

Abstract

Carbon nanofibers and nanotubes are currently being utilized as active elements in acoustic sensors for emerging microelectromechanical systems and nanoelectromechanical systems technologies. A methodology for measuring the displacement of carbon nanofibers in combination with heterodyne interferometry is reported here. Experimental results show that… (More)
