“…It must be pointed out in the first instance that, unlike several literature reports regarding DMFC devices, our measures were carried out not in a flow mode and above all at temperature higher than room temperature (however not exceeding 60 C, as was the case for the majority of other authors working in this field [16][17][18][19][20][21]). Our decision was not made by chance as the intention was to explore the possibility of making measurements of ethanol or methanol as simply as possible using highly compact instruments in order to perform measures at room temperature.…”

“…First of all however, to check the Optimized Applied Potential (OAP), the supplied current (SC) by the cell [18,19,21] for one fixed alcohol concentration at different applied potentials between the electrodes was recorded (see Fig. 5(a) and (b)).…”

“…Of course, practically all the studies performed on direct methanol or ethanol fuel cells refer to: the power performance, the engineering and the electrochemical reactions underlying their performance and their possible use as devices capable of converting chemical energy into electrical energy. However, recently, a relatively small number of publications have described also the possible use of DMFCs as electrochemical sensors for methanol [16][17][18], in some cases proposing quite sophisticated devices, for example, cells constructed with two anodes face to face [19], or bioelectrochemical fuel cell enzyme sensors [20]. Nevertheless, these works deal essentially, as we have seen, with the development of original, and often very interesting, devices [16,17], or else provide a detailed description of the various operating modes [21], rather than evaluate the real potential of simple and thus cheap DMFCs to be used for essentially analytical purposes and their effective application in the analysis of real matrixes, or even for the comparison with other types of electroenzymatic sensors already widely used in the field of methanol or ethanol analysis.…”

A small direct catalytic methanol 'fuel cell' was used for analytical purposes. Three different formats were investigated for methanol and ethanol determination: two different Open Circuit Voltage (OCV) formats and a potentiostatic (i.e. amperometric) format; the latter was used if the current supplied by the cell was recorded. The measurement times using one or other of these three formats were much different. The time required by the potentiostatic format was more short for a suitable analytical measurement. The cell was used to check ethanol content in several commercial wine and beer samples and the possibility of using the fuel cell for the analytical measures in real samples, discussed. Lastly the results were compared with those obtained using two conventional amperometric enzyme sensors and statistical tests carried out. (C) 2016 Elsevier Ltd. All rights reserved

Research into operational aspects of mini unmanned aerial vehicles (UAV) and structural health monitoring systems (SHM) is being conducted at the Defence Science and Technology Organisation and La Trobe University. A fundamental area of interest is investigating the problems associated with miniaturization of the control and health monitoring sensors for such systems. While many technologies for UAV and SHM systems can be, and have been, adapted from those currently available in large manned aircraft; cost, weight, and size constraints have prevented mini UAVs from including many of the robustness mechanisms common to larger aircraft. Moreover, the ubiquitous nature of the sensing requirements for SHM systems has limited their uptake, due mainly to the same issues of cost, weight and size. This paper details the design of a reconfigurable multivariable MEMS (Micro Electro Mechanical System) sensor array to address these issues. This array is comprised of multiple instances of identical sensors, which can be dynamically reconfigured to achieve the desired measurand(s) with tradeoffs against accuracy. The available measurands include such items as; accelerations, rotational rates, magnetic fields (all in X, Y and Z directions), temperature and pressure. This paper presents the design of a reconfigurable multivariable MEMS sensor array together with simulation results.
