Structural health management (SHM) of safety-critical structures requires multiple capabilities: sensing, assessment, diagnostics, prognostics, repair, etc. This paper presents a capability for self-organising diagnosis by a group of autonomous sensing agents in a distributed sensing and processing SHM network. The diagnostics involves acoustic emission waves emitted as a result of a sudden rel...

Tris-1,10-phenanthroline manganese(II) complex was synthesized by microwave irradiation. The synthesized complex was characterized by UV-visible and FT-IR spectroscopy. Its electrochemical behaviour was examined by cyclic voltammetry (CV). The tris-1,10-phenanthroline manganese(II) complex was used for the electrochemical sensing of catechol. The manganese ion gets reduced as the oxidation of c...

With the advent of computational electromagnetics and increasing speed and power of computing, it is promising where modelling in microwave remote sensing can be pursued with more realistic physical configuration. This project focuses on new approaches in extending current basic computational electromagnetics to the application in microwave remote sensing as well as extension of modelling capab...

A mediatorless sulfide electrochemical sensing platform utilising a novel nanocopper-oxide screen-printed electrodes (CuSPE) is reported for the first time. The state-of-the-art screen-printed electrochemical sensors demonstrate their capability to quantify sulfide within both the presence and absence of an array of interferents with good levels of sensitivity and repeatability. The direct sens...

Data saving capability of “Compressed sensing (sampling)” in signal discretization is disputed and found to be far below the theoretical upper bound defined by the signal sparsity. On a simple and intuitive example, it is demonstrated that, in a realistic scenario for signals that are believed to be sparse, one can achieve a substantially larger saving than compressing sensing can. It is also s...

The paper describes the development of flexible lightweight highly sensitive film-based sensors capable of monitoring pressure, deformation, temperature and humidity. In particular, we present a family of the developed simple devices that successfully adopted polycarbonate films covered with organic molecular conductors as conductive sensing components. Proof-ofconcept experiments with these pr...

The ever increasing demand for in situ monitoring of health, environment and security has created a need for reliable, miniaturised sensing devices. To achieve this, appropriate analytical devices are required that possess operating characteristics of reliability, low power consumption, low cost, autonomous operation capability and compatibility with wireless communications systems. The use of ...

Now that billions of people carry sensor-enabled mobile devices (e.g., smartphones), employing powerful capability of such commercial mobile products has become a promising approach for large-scale environmental and human-behavioral sensing. Such a new paradigm of scalable context monitoring is known as opportunistic sensing, and has been successfully applied to a broad range of applications. I...
