“…Therefore, sintering of conductive inks such as Ag paste is a critical process for the fabrication of conductive patterns . In general, laser‐assisted sintering is preferred because it only heats a specific area, thereby reducing the thermal damage to the structure . As the conductive ink absorbs the laser energy, the resulting heat buildup evaporates the resin binder (polymer) and this causes interconnection between the metal particles; hence, conductive inks ensure electrical conductivity .…”

Recently, several investigations have been reported on hybrid technology that embeds circuits on 3D printed models during processing. A new direct fabrication method of conductive patterns on 3D printed structure with laser is suggested for process simplicity. In order to fabricate conductive patterns, a conventional 1064 nm fiber laser is utilized to selectively remove the polymer and connect the copper particles to each other. The fabricated patterns achieve high conductivity with a resistance of 0.15 Ω cm À1 when the length of the pattern is 50 mm. In this study, the surface property changes of the 3D printed structure through laser irradiation are presented and the influences of the laser parameters, including average power, scanning mode (repetition rate), scanning speed, and scan line spacing, on the process efficiency are investigated. Finally, a prototype of an electronic circuit is made and demonstrated for powering up LEDs. The proposed method allows to easily and rapidly fabricate high conductive patterns on complex 3D structures by combining the additive manufacturing technology with laser irradiation.

A long-standing industrial problem is tackled with an industrial internet of things (IIoT) application. This thesis presents the hardware design and development of a wireless sensor network for monitoring ground engaging tools of earth processing equipment. This work addresses several challenges in the hardware design. The challenges included establishing wireless communications from within a metallic enclosure, Investigating the effect of antenna tuning on the link budget, designing a protective package for the sensor node (SN) to withstand vibrations and mechanical shocks, and creating a low-power design that allowed for a minimum battery life of one year.Furthermore, this work puts forward the design of novel application-specific sensors including a low-power ferrous-selective proximity sensor and a low-cost capacitive wear-level sensor.Hardware designs were evaluated with laboratory and field tests. The conducted tests demonstrated the SN's functionality and performance in harsh operating conditions. The journey from problem definition and to successful field testing of the complete wireless sensing solution is covered in this thesis.In addition, a novel energy-efficient approach to wireless real-time sensing is presented. For an SN transmitting samples of a discrete time-series in real-time, its DisclaimerThis work was made possible through the software developed by Galal Hassan. His work on the shovel project covered firmware development for the sensor node, software development for the sink, and setting up the back-end cloud server including the dashboard. Furthermore, Galal has contributed significantly to the success of the shovel project by developing an energy-efficient MAC protocol [1] which allowed for satisfying the life-time requirement of the sensor nodes.

“…11 Dispenser printed smart fabrics have also been demonstrated for the functions of sound emission, 12 electroluminescence, 13 colour change, 14,15 stretch sensing 16 and proximity sensing. 17 However, each of these demonstrators was printed as single devices with individually programmed printer paths for each layer – this is unsuitable for the targeted creative industry users because of the complexity involved and the specific printing knowledge required. This article presents a universal hardware and software platform dedicated to the design and realisation of smart fabrics for the creative industry.…”

A hardware and software platform is presented enabling the design, and realisation via printing, of smart fabrics. The cultural and creative industries are an important economic area within which designers frequently utilise fabrics. Smart fabrics offer further creative opportunities to the cultural and creative industries, but designers often lack the required specialist knowledge, in electronics, software and materials, to produce smart fabrics. The software platform offers the ability to perform design, layout and visualisation of a smart fabric using a library of standard smart fabric functions (e.g. electroluminescence) so specialist expertise is not needed. Operation of the smart fabric can be simulated, and parameters can be set for smart fabric control electronics, which consists of standard circuit board modules. The software also provides driver code for the hardware platform to print the smart fabric. The hardware platform consists of a bespoke dispenser printer; functional inks are deposited via a pneumatic syringe controlled by the driver software, allowing bespoke rapid prototyped smart fabrics to be printed. Operation of the software and hardware system is demonstrated by the realisation of an interactive smart fabric consisting of electroluminescent lamps controlled by a proximity sensor. The modular electronics are used to control the smart fabric operation using embedded code generated by the software platform. For example, the blink rate of the electroluminescent lamp can be adjusted by the proximity of a hand. This control is achieved by the use of intuitive drop-down menus and input/output selections by the creative user. At present, the platform allows the design, print and implementation of smart fabrics incorporating the functions of colour change, electroluminescence, sound emission and proximity sensing. The platform can be expanded to add additional functions in the future and the printer will be compatible with new inks developed for screen and inkjet printing.
