Abstract The dissemination of sensors is key to realizing a sustainable, ‘intelligent’ world, where everyday objects and environments are equipped with sensing capabilities advance the sustainability quality our lives—e.g. via smart homes, cities, healthcare, logistics, Industry 4.0, precision agriculture. realization full potential these applications critically depends on availability easy-to-make, low-cost sensor technologies. Sensors based printable electronic materials offer ideal...
For some professionally, vocationally, or technically oriented careers, curricula delivered in higher education establishments may focus on teaching material related to a single discipline. By contrast, multidisciplinary, interdisciplinary, and transdisciplinary (MITT) results improved affective cognitive learning critical thinking, offering learners/students the opportunity obtain broad general knowledge base. Chemistry is discipline that sits at interface of science, technology,...
3D printing of antennas on removable fingernail for on-body communications at microwave and millimetre waves is proposed. Aerosol Jet technology, a fine-feature material deposition solution, has been used to directly print microstrip patch an acrylonitrile butadiene styrene (ABS) finger nail substrate. Two have printed assessed, one operating 15 GHz the other 28 GHz. Nanoparticle conductive silver ink employed create corresponding transmission line using Optomec machine. The inks are then...
The use of additive manufacturing (AM) techniques for the fabrication 3-D fractal monopole antennas is presented. printing (3-D P) designs based on Sierpinski concept studied, and performance discussed.

Abstract Permeation barrier films are critical to a wide range of applications. In particular, for organic electronics and photovoltaics not only ultra-low permeation values required but also optical transparency. A laminate structure thereby allows synergistic effects between different materials. Here, we report on combination chemical vapor deposition (CVD) atomic layer (ALD) create in scalable fashion few-layer graphene/aluminium oxide-based nanolaminates. The resulting ~10 nm contiguous,...

A circularly polarized patch antenna fabricated using commercially available, low-cost, printers is described. Two additive processes are combined for the fabrication: stereolithography (SLA) and inkjet printing of silver inks. widely available SLA 3D printer employed to fabricate substrate antenna. Inkjet used deposit metallic layers radiating element on substrate. The two machines very low-cost in comparison those previously reported work. Good adhesion patterns substrates observed....
Transparent barrier films such as Al 2 O 3 used for prevention of oxygen and/or water vapour permeation are the subject increasing research interest when encapsulation flexible photovoltaic modules.However, existence micro-scale defects in surface topography has been shown to have potential facilitate ingress, thereby reducing cell efficiency and causing internal electrical shorts.Previous work that small (≤3 μm lateral dimension) were less significant determining ingress.In contrast, larger...

Abstract Electrical and electronic equipment (EEE) have revolutionized our lives, however, their associated waste (WEEE) presents a global challenge because at this time EEE relies heavily on metals that are not commonly found in the living environment (Biosphere), which find way into during both production/disposal of EEE/WEEE. The use organic components is increasingly common, particularly with growing interest flexible electronics. Here we describe an approach to device design employing...
Flexible Cu (In, Ga) Se2 (CIGS) solar cells are very attractive renewable energy sources because of their high conversion efficiencies, low cost potential and many application possibilities. However, they at present highly susceptible to long term environmental degradation as a result water vapor ingress through the protective encapsulation layer absorber layer. The basic methodology prevent permeation is combine an oxide (e.g. AlOx) coating with suitable polymer substrates. Nevertheless,...

Film processing procedures by means of Roll-to-Roll (R2R) for barrier coatings can often result in PV films being manufactured with significant quantities defects, which results lower efficiency and a short life span. In order to improve the process yield product efficiency, it is desirable develop an inspection system that detect transparent film defects production line during processing. Off-line detection difficult time consuming. Consequently, implementing accurate in-situ environment...
Thin film flexible electronics refer to a class of electronic devices built on substrates.
