The large interest in utilising fibre Bragg grating (FBG) strain sensors for minimally invasive surgery (MIS) applications to replace conventional electrical tactile sensors has grown in the past few years. FBG strain sensors offer the advantages of optical fibre sensors, such as high sensitivity, immunity to electromagnetic noise, electrical passivity and(More)
Surface plasmon resonance (SPR) is a novel optical sensing technique with a unique ability to monitor molecular binding in real-time for biological and chemical sensor applications. Interferometry is an excellent tool for accurate measurement of SPR changes, the measurement and comparison is made for the sensitivity, dynamic range and resolution of the(More)
This study reports research findings on the use of custom animation to teach electrical, electronic & system engineering students enrolling in Fiber to the Home (FTTH) system course at the National University of Malaysia. Even with over 10 years of experience in teaching the fiber optic course, the authors found it very difficult to clearly describe the(More)
The purpose of this study is to identify the influencing factors in selecting a university and course program among Malaysian matriculation students. The study was conducted at two matriculation colleges in south Malaysia. Questionnaire was distributed to students from Negeri Sembilan Matriculation College (NSMC) and Malacca Matriculation College (MMC).(More)
A POF flow injection cell is developed to determine nitrite in aqueous based on spectrophotometric method. The jacket of the POF is used as a chamber cell with 10mm core as pathlength. The direct absorbance spectrophometric principle is applied in this work and a range of 400nm to 650nm wavelengths were selected as the nitrite absorption region. Sample of(More)
The study of binding affinity is essential in surface plasmon resonance (SPR) sensing because it allows researchers to quantify the affinity between the analyte and immobilised ligands of an SPR sensor. In this study, we demonstrate the derivation of the binding affinity constant, K, for Pb2+ and Hg2+ ions according to their SPR response using a(More)
A novel and efficient absorption line recovery technique is presented. A micro-electromechanical systems (MEMS) mirror driven by an electrothermal actuator is used to generate laser intensity modulation through the mirror reflection. Tunable diode laser spectroscopy (TDLS) and photoacoustic spectroscopy (PAS) are used to recover the target absorption line(More)
