    Resumen
    The work looks at how regions design policies to facilitate the transition of regional innovation systems to Industry 4.0. The research analyses how regional Industry 4.0 policies should take into account the integration of the position of the regional productive system into international supply chains, the games of legitimacy and power of the actors involved in the innovation system, the institutional structures that allow the exchange of knowledge on Industry 4.0. between the agents and the connection between the synthetic knowledge base (engineering driven) and the analytical knowledge base (science driven) of the region. Through a detailed case study of the background, structure and impact of Industry 4.0 in the Spanish regions of the Basque Country and Catalonia, the work demonstrates how it is not possible to define a policy of promoting Industry 4.0 that is generalizable to all regions and how each region will have to adapt the design and implementation of its Industry 4.0 policies to the specific characteristics of its regional innovation system. Therefore the replication of policies from other regions will not be an effective mechanism for promoting Industry 4.0 since the transition to Industry 4.0 is a very regional specific and diverse process.

    Resumen
    Los simuladores de vehículos se emplean ampliamente en disciplinas como la Fórmula 1, fabricantes de vehículos comerciales, vuelos militares o civiles, etc. Permiten evaluar el diseño del vehículo de forma más rápida y barata que por los métodos tradicionales, e incluso permiten hacerlo antes de que el prototipo esté fabricado. Estos simuladores de conducción se componen por un hardware, con el que interactúa un conductor y, un software que controla el modelo matemático del automóvil y la pista, encargándose de resolver la física entre ambas partes y procesando la imagen que se muestra en pantalla. El circuito en el que discurre el coche juega un papel fundamental en todo esto, por lo que en este trabajo se propone un método de bajo coste que permita modelar pistas de carreras, y que, posteriormente, se integre en el simulador de alta fidelidad ubicado en el centro Automotive Intelligence Centre ¿ AIC en Amorebieta, País Vasco, España. El modelo 3D presentado corresponde con el Circuito de Vilariño Motorsport (Olaberria), obtenido por fotogrametría aérea con un dron consiguiendO una resolución de 3,4mm/px y un error máximo de 50mm, siendo además un método rápido y de bajo coste respecto a otros sistemas de captura de datos como es el LIDAR.

    Resumen
    Purpose The purpose of this study is to explore a methodology for connecting microelectromechanical system sensors - i.e. inertial measurement unit (IMU) - to an Arduino-based microcontroller, using graphene-based conductive filament and flexible thermoplastic polyurethane (FTPU) filament and low-cost dual material extrusion technology. Design/methodology/approach A series of electrical tests were carried out to determine the maximum resistance the conductive paths may take to connect printed circuit boards (PCB). To select the most suitable printing material, three types of conductive filaments were examined. Then an experiment was carried out to find the best printing parameters in terms of printing speed, printing temperature and layer height to minimise resistivity. The size of the conductive path was also analysed. A final prototype was designed and printed according to optimised printing settings and maximum allowable resistances for each line and considering different geometries and printing strategies to reduce cross-contamination among paths. Findings For the Black Magic 3D conductive filament, the printing speed and layer height played a significant role regarding resistivity, while the printing temperature was not very important. The infill pattern of the conductive paths had to be aligned with the expected current path, while using air gaps between two adjacent paths resulted in the best approach to reducing cross-contamination. Moreover, the cross-section size of

    Resumen
    Wearable electronics make it possible to monitor human activity and behavior. Most of these devices have not taken into account human factors and they have instead focused on technological issues. This fact could not only affect human¿computer interaction and user experience but also the devices¿ use cycle. Firstly, this paper presents a classification of wearable design requirements that have been carried out by combining a quantitative and a qualitative methodology. Secondly, we present some evaluation procedures based on design methodologies and human¿computer interaction measurement tools. Thus, this contribution aims to provide a roadmap for wearable designers and researchers in order to help them to find more efficient processes by providing a classification of the design requirements and evaluation tools. These resources represent time and resource-saving contributions. Therefore designers and researchers do not have to review the literature. It will no be necessary to carry out exploratory studies for the purposes of identifying requirements or evaluation tools either.

    Resumen
    This paper presents a user-centered methodology to co-design and co-evaluate wearables that has been developed following a research-through design methodology. It has been based on the principles of human-computer interaction and on an empirical case entitled "Design and Development of a Low-Cost Wearable Glove to Track Forces Exerted by Workers in Car Assembly Lines" published in Sensors. Insights from both studies have been used to develop the wearable co-design domino presented in this study. The methodology consists of different design stages composed of an ideation stage, digital service development and test stages, hardware development and test stage, and a final test stage. The main conclusions state that it is necessary to maintain a close relationship between human factors and technical factors when designing wearable. Additionally, through the several studies, it has been concluded that there is need of different field experts that should co-design and co-evaluate wearable iteratively and involving users from the beginning of the process.

    Resumen
    Shin pads are part of the mandatory equipment footballers must wear so as to prevent lesions. Most players wear commercially available shin pads made from a variety of common materials (polypropylene or polyethylene) and high-resistance materials (glass fibre, carbon fibre or Kevlar) using traditional manufacturing techniques. Additive manufacturing was used years ago to deliver customised rigid shin pads, but they did not offer any significant advantage in terms of materials or design compared to traditional shin pads. This project analyses a novel approach to the design and manufacture of shin pads for football players that combines existing digitisation tools, lattice structures and a multi-material additive manufacturing device. A total of 24 different additive manufacturing geometries were evaluated using a customised rig where a 1-kg impactor was released from several heights (100-400 mm). The impact acceleration, the transmitted force to the leg and penetration were calculated. Results were compared against two commercially available shin pads. Results show that two of the additive manufacturing specimens tested at the highest drop height had lower impact accelerations than commercial shin pads. They had an acceleration reduction between 42% and 68% with respect to the commercial shin pads. Regarding the penetration, the improvement achieved with additive manufacturing specimens ranged from 13% to 32%, while the attenuation and the contact times were similar.

    Resumen
    Additive Manufacturing devices or 3D printers allow the possibility of creating almost anything. One of the most promising fields of application are wearable devices, which can be directly printed on textiles. This paper aims to study adhesion forces and warping effects when depositing a polymer onto a textile with a low-cost extrusion 3D printer. To achieve this, two different polymers (PLA and Filaflex) and six of the most common textile materials were selected. L-shaped specimens were printed by combining the two polymers and the six textiles. Most of the common printing settings were fixed for both materials, while the layer quality was 0.1 mm and 0.2 mm. Once printed, they were inspected with a Coordinate Measuring Machine and the deformation of each specimen was quantified by calculating their maximum and minimum displacements. Afterwards, each specimen was axially tested to evaluate the adhesion forces between the polymer and the textile. In terms of warping, flexible filament showed the lowest values independent of printing quality (0.56 mm and 0.3 mm) relative to the rigid filament (0.73 mm and 0.8 mm). In terms of adhesion, the combination of a porous textile and a flexible filament got the highest values, regardless of the layer height selected. The conclusion of this study is that polymer textile deposition can be a real manufacturing strategy that should be considered when thinking about the design of a wearable device to be worn on the body.

    Resumen
    Introduction: In recent years, the use of 3D printing in medicine has grown exponentially, but the use of 3D technology has not been equally adopted by the different medical specialties. Published 3D printing activity in general thoracic surgery is scarce and has been mostly limited to case reports. The aim of this report was to reflect on the results and lessons learned from a newly created multidisciplinary and multicenter 3D unit of the Spanish Society of Thoracic Surgery (SECT). Methods: This is a pilot study to determine the feasibility and usefulness of printing 3D models for patients with thoracic malignancy or airway complications, based on real data. We designed a point-of-care 3D printing workflow involving thoracic surgeons, radiologists with experience in intrathoracic pathology, and engineers with experience in additive manufacturing. Results: In the first year of operation we generated 26 three-dimensional models out of 27 cases received (96.3%). In 9 cases a virtual model was sufficient for optimal patient handling, while in 17 cases a 3D model was printed. Per pathology, cases were classified as airway stenosis after lung transplantation (7 cases, 25.9%), tracheal pathology (7 cases, 25.9%), chest tumors (6 cases, 22.2%) carcinoid tumors (4 cases, 14.8%), mediastinal tumors (2 cases, 7.4%) and Pancoast tumors (one case, 3.7%). Conclusion: A multidisciplinary 3D laboratory is feasible in a hospital setting, and working as a multicenter group increases the number of cases and diversity of pathologies thus providing further opportunity to study the benefits of the 3D printing technology in general thoracic surgery.

    Resumen
    Wearables are gaining widespread use and technologies are making it possible to monitor human physical activity and behaviour as part of connected infrastructures. Many companies see wearables as an opportunity to enhance worker safety since they can monitor their workers' activity in real life scenarios. One of the goals of this technology is to integrate existing electronic components, such as sensors or conductors, in order to create fully wearable systems. This integration is constrained not only by technical factors but also by user requirements and internal company standards. This paper considers such constraints and presents preliminary research for the design of a wearable glove as a new tool to track forces exerted by workers in car assembly lines. The objective of the glove is to measure forces and compare these to maximum forces already identified by the company. Thus, the main objectives are to: (1) integrate the components based on the requirements of the users and the context of application, and (2) provide a new tool that can be used in situ to track workers. This study was carried out in close collaboration with Volkswagen through a human-centred iterative design process. Thus, this paper presents the development of a wearable device glove based on a specific design methodology where both the human and technological aspects are considered.

    Resumen
    Many industrial companies are now getting on board the new industrial revolution dominated by data acquisition, digitalization and other new technologies. Wearables combine the features of some of the most popular technologies of this revolution: they can monitor specific body regions by tracking information anywhere and anytime. Wearable systems for hands represent a special field of interest since they are the main body region involved in industrial tasks. This paper surveys such wearable systems based on the data from the last years. It collects information about the most important components they incorporate and analyses their features considering that they are devices aimed to be worn on the body. Thus, this paper is addressed to researchers who want to understand what a wearable is and which the main components and characteristics should incorporate, and also, those who want to explore new trends in this research field.

    Resumen
    The increasing relevance of occupational injuries and illness related to lean manufacturing strategies in automotive assembly lines brings an increasing interest in this industry by the research and development of new tools and methods for the evaluation and prevention of work-related musculoskeletal disorders (WMSDs). However, few studies have focused on assessing the exposures to the hand region whereas disorder in this region remain at the primary tier of the prevalence ranking. Herein, this paper presents a low-cost, wearable inertial measurement unit (IMU) to measure workplace demands. This technology was selected after analysing an assessment scale composed of seven of the common ergonomic assessment tools and methods. After a brief verification through a laboratory goniometry experiment, eleven joint angles of a volunteer¿s hand were measured. The results indicated that the mean difference between the values measured by participants and the values obtained directly from the wearable is 2.44°, which has the same accuracy level of the commercial products. The proposed device is scalable enough to be iterated by further improvements, including conductive fabric 3D printing technology.

    Resumen
    Chesbrough coined the term open innovation in 2003, and after a decade of research he redefined it as ¿a distributed innovation process, based on purposively managed knowledge flows across organizational boundaries, using pecuniary and non-pecuniary mechanisms, in line with the organization¿s business model¿ (Chesbrough and Bogers, 2014). Understanding open innovation helps to realize how sharing knowledge with internal and external stakeholders can promote innovation. The essence of such knowledge sharing by internal and external stakeholders build relationships that are based on common interests and goals. Although open innovation has been a hot topic within business, design and innovation management, it is still ill defined and companies struggle with smooth implementation of open innovation practices into their daily operations. Different perspectives exist on the need for openness, antecedents of open innovation, different typologies of practices, how to determine which one fits each company and challenge, the processes for implementation and the roles that design and designers can play in these processes. The main aim of this conference track is to debate some of these emerging issues and position designers within this context. Therefore, within this track, the role of design, the designer and design management are considered and potential drivers for implementation of open innovation within organisations discussed.
