Digital inkjet printing (IJP) can greatly reduce the manufacturing cost and waste of flexible large-area electronics by adding micro-fine patterns onto plastic foils. Advanced system design using IJP has been limited by the lack of an electronic design automation (EDA) approach. An EDA approach based on a vector-based layout drawing requires parameterized IJP design rules. This study proposes a layout-to-bitmap (L2B) conversion procedure and line-based design rules that leverage the existing circuit layout EDA tools for advanced IJP designs. The L2B conversion is accomplished by optimizing the parameters of the horizontal and vertical lines by varying the drop spacings and platen temperatures. Next, the line-based layouts are converted to bitmap files which are used as IJP input data for printing multiple metal layers. This study systematically investigated the development of an IJP process employing Ag nanoparticles. The physical characteristics of the proposed process were evaluated based on theories concerning inkjet-printed bead formation. The design rules for fabricating printed thin-film transistor (TFT) circuits were documented. Documentation is the first step in creating an IJP process design kit for advanced electronics design. Using the optimized L2B conversion procedure and the design rules, a 10 × 10 array of printed organic TFTs was fabricated to demonstrate the reliability of the developed process. Additionally, the fabricated printed organic TFTs indicated that the proposed process could be extended to large-scale system designs.

As robot technology is disseminated from special fields such as factory production to everyday fields such as home use, community work, and entertainment, working space of robots also expands from dedicated area such as factory sites to ordinary living space. Combining this technology shift and the popularized public Internet suggests the emergence of new robot applications. The Internet, however, as its nature, is not suitable for tight coupling of processes among robots and computers. An approach different from simple expansion of current robot communication technology is thus necessary. After discussing the essentials of communication, i.e., closed and open networks, and tight and loose couplings of processes, we propose combining Web Services technology and autonomous robot technology. We present several cases to examine this approach. The applicability of Web Services to robot communication is confirmed through implementation. Feasible applications are studied using application instances combining autonomous robots with the Internet. Feasibility is also examined from Web Services technology point of view.

Robotics technology is very useful for the lives of many people today. Almost all aspects of his life utilize robotics technology according to the required field. The development of robotics technology has become a higher quality of human life. Perhaps robotics are still less popular among the general public who still thinks robotics are humanoid robots (robots or human machines). Robotics has been widely implemented in the real world ranging from the fields of industry, medicine, entertainment, security, to household appliances. In the field of security, robotics has an important role. As the robot principle itself is tireless and has little tolerance, the product in robotics in the security field can be a very useful tool. In addition to facilitate human insecurity, robotics products can also facilitate human in various jobs, such as in the locking doors or walls of anyone who already exists. The development of robotics is in line with the development of computer vision which is increasing its application in everyday life. With this research, is expected to improve security and comfort in the security room. The design of this system using electronic door locks, open source OpenCV and webcam as a unit component.

Gone are the days of hand-drawn elevations and sketchy illustrations of vanished monuments: by integrating laser scans and photogrammetry with graphic images and written documents, three-dimensional digital modeling can produce the most evocative illustrations of architecture to date. In the past decade or so, architectural historians have turned to such modeling as a means of reverse engineering parts of buildings as well as whole buildings to visually examine change over time. The innovations of 3D modeling are particularly generative for research on the medieval European built environment, whose corpus has been significantly altered and diminished by time. In addition to offering new insights from the fragments of old or vanished structures, these technologies allow for analyses that permit a new way of seeing and interacting with materials, interior spaces, urban environments, and...

Multi-metal additive manufacturing of selectively doped 316 L stainless steel-copper composite using hybrid laser powder bed fusion

Highlights: High-definition scanning and 3D printing have been used as tools in the detection of heritage pathologies, as well as in the study of materials. The Carcabuey castle has been digitized and the volumetric data recovered from the study of its materials typology and its stereotomy, obtained with laser scanning. The study of construction and material phases, and the pathologies produced by them, has been carried out from the 3D printing of the heritage structure parts. Abstract: Precise documentation is essential to carry out the restoration and enhancement processes of protected heritage contexts. Data collection has been increasingly perfected, to the point of being able to perform virtual recreations of complex historical sites, in order to carry out in-depth studies and analyses. An example is Carcabuey Castle (Cordoba, Andalusia), a large fortress with important medieval structures. It is a monumental site of the so-called "Frontier Castles", which were located between the Kingdom of Aragon, and the Nasrid Kingdom of Granada. With the aim of restoring it and highlighting its value, an in-depth study was developed for its conservation and subsequent intervention. The data collection included terrestrial laser scanning and vectorising all the structures, as well as a complex and complete photogrammetric survey. From these previous data and carrying out a deductive analytical methodology, a model was generated which, after being printed in 3D (different models at different scales of detail), would allow the volumes, materials and textures which make up the castle, to be studied. The multidisciplinary team, composed of architects, archaeologists, historians and engineers, made it possible to provide multifaceted and inclusive character to all the work, both in the study of pathologies based on the models, and in the construction phases, detected by the stereotomy of the ashlars, or chemical composition of mortars. Since then, with all the data obtained in the research, summarised in this article, it has been possible to carry out a correct diagnosis for the restoration and enhancement of the heritage site.

Three-dimensional (3D) bioprinting, as a freeform biomedical manufacturing approach, has been increasingly adopted for the fabrication of constructs analogous to living tissues. Generally, materials printed during 3D bioprinting are referred as bioinks, which may include living cells, extracellular matrix materials, cell media, and/or other additives. For 3D bioprinting to be an enabling tissue engineering approach, the bioink printability is a critical requirement as tissue constructs must be able to be printed and reproduce the complex micro-architecture of native tissues in vitro in sufficient resolution. The bioink printability is generally characterized in terms of the controllable formation of well-defined droplets/jets/filaments and/or the morphology and shape fidelity of deposited building blocks. This review presents a comprehensive overview of the studies of bioink printability during representative 3D bioprinting processes, including inkjet printing, laser printing, and micro-extrusion, with a focus on the understanding of the underlying physics during the formation of bioink-based features. A detailed discussion is conducted based on the typical time scales and dimensionless quantities for printability evaluation during bioprinting. For inkjet printing, the Z (the inverse of the Ohnesorge number), Weber, and capillary numbers have been employed for the construction of phase diagrams during the printing of Newtonian fluids, while the Weissenberg and Deborah numbers have been utilized during the printing of non-Newtonian bioinks. During laser printing of Newtonian solutions, the jettability can be characterized using the inverse of the Ohnesorge number, while Ohnesorge, elasto-capillary, and Weber numbers have been utilized to construct phase diagrams for typical non-Newtonian bioinks. For micro-extrusion, seven filament types have been identified including three types of well-defined filaments and four types of irregular filaments. During micro-extrusion, the Oldroyd number has been used to characterize the dimensions of the yielded areas of Herschel-Bulkley fluids. Non-ideal jetting behaviors are common during the droplet-based inkjet and laser printing processes due to the local nonuniformity and nonhomogeneity of cell-laden bioinks.

As a new generation of printing technology, thermal inkjet (TIJ) has been widely adopted to meet the increasing demand for high printing quality and efficiency at an affordable price. High air barrier tubes play an important role in the reliable operation of the printhead in a commercial thermal inkjet printer. Desired tube qualities include low stiffness and low pressure drop, along with others. Tube stiffness and pressure drop can be lowered through the selection of proper tube layer configuration, geometry, and material properties. However, the existing tube design practice is highly heuristic and design results are not optimal. In this work, using TIJ design as a real world example, a comparative study is conducted to support the use of formal methods in design applications previously governed by heuristic/trial-and-error approaches. Two cases using different optimization strategies are investigated: Case A—performance-based optimization strategy; and Case B—robust design-based optimization strategy. A comparison of their results with the current practice shows that the optimization strategies can greatly improve the efficiency of the current tube design process. More important, the optimization strategy with variation consideration yields robust results and provides much richer design knowledge to support designers with various experiences to make better decisions.

The smart city concept has been used by many cities in Indonesia as means to ease people lives. Yogyakarta, as the province with the highest ratio of area and number of tourism visits in Indonesia, is a province that has been quite hit by the COVID-19 pandemic. One of the affected parties are Small and Medium Enterprises (SMEs). To anticipate this, the Yogyakarta City Government launched the Jogja Smart Service (JSS) application. JSS was launched with the aim of facilitating public services, and one of its features namely Gandeng Gendong to bring together the SMEs community with potential buyers. This paper will describe the communication process of JSS application by Yogyakarta City Government and SMEs actors. This research departs from the impact of the Covid-19 pandemic felt by the SMEs of Yogyakarta City on the economy in their lives. After the pandemic, the Yogyakarta City Government tried to foster smart economy as one of the smart city branch concepts. Nonetheless, there are still many challenges. In anticipation of a repeat of the economic impact of the COVID-19 pandemic, the SMEs actors must be able to quickly adopt the Jogja Smart Service application. The results of the research obtained are the process of communication by Yogyakarta City Government and SMEs actors in the early majority stage. The SMEs actors are at the confirmation stage. The confirmation determines that SMEs actors continue to use the Jogja Smart Service application but need more socialization and training.

This paper describes the software platform design of a personal service robot with application to healthcare scenarios. The platform was designed after exploration of both the service application and software architectural design spaces. The service application considered here is a comprehensive medication management service which evolved to be one of the more complex use cases in the Healthbots project. While algorithms and user studies of human robot interaction are reported in the literature, there is less attention given to related software frameworks and tools, which are addressed in this paper. The paper focuses and solves numerous design challenges to achieve the desired functionality of the medication management service with its complex set of workflow and contextual requirements which were not present in the software platforms we had designed. The robots were used in a real world deployment scenario at an Aged Care Facility. Scenarios and results from a field trial are presented to enable the research community to understand the technological and engineering challenges of deployment of the robot system and the level of fluid integration required to achieve the desired goals of functionality and robustness in the real world.

Multiwalled carbon nanotubes (MWCNTs) are attractive materials for realizing sensors, owing to their high aspect ratio associated with excellent mechanical, electronic, and thermal properties. Moreover, their sensing properties can be tuned by introducing functional groups on their framework and adjusting the processing conditions. In this paper, we investigate the potential of functionalized CNTs for humidity and temperature sensing by optimization of the functionalization, the processing conditions and the printing conditions. The morphology of the differently functionalized MWCNTs is investigated by infrared spectroscopy (IR), scanning electron microscopy, thermogravimetry (TG) and TG-coupled mass-spectrometric studies. Using the functionalized MWCNTs, films were fabricated with different numbers of layers (4, 6, 8, 10 layers) via inkjet printing on a flexible polyimide substrate containing an interdigital microelectrode. The influence of hydrothermal effects was investigated. The sensitivity to humidity is higher for films prepared with MWCNTs functionalized with a high sonication amplitude and a bigger number of layers due to enhancements of hydrophilicity and water mobility. A higher sensitivity to temperature is achieved by a low sonication amplitude and a small number of layers. For the encapsulation of the temperature sensor against humidity, a Bectron layer is proposed, which reduces also the hysteresis effect. This study demonstrates the efficiency of carboxylic functionalized MWCNTs deposit by inkjet printing for realization of sensitive and cost-effective humidity and temperature sensors. It provides a real example for the interesting contribution of functionalization procedures to the sensing properties of MWCNTs films.

The last few years have been characterized by the continuous development of information and communication technologies, robotics technologies, and home automation technologies. The number of application areas for such technologies is increasing, especially in fields rather outside the pure industrial scenario, often identified as “service applications.” These are healthcare, public service provisions, social services for disadvantaged citizens, technical aids for promoting the independence of disabled and elderly people, and many others. With this joint research Scuola Superiore Sant‘Anna and Waseda University, starting from the current availability of several mechatronic prototypes in their research laboratories, intend to validate different telecommunication tools for the remote control of mechatronic systems by demonstrating the feasibility and potential benefits deriving from the integration of such technologies.
