A Wearable Textile 3D Gesture Recognition Sensor Based on Screen-Printing Technology

[EN] Research has developed various solutions in order for computers to recognize hand gestures in the context of human machine interface (HMI). The design of a successful hand gesture recognition system must address functionality and usability. The gesture recognition market has evolved from touchpads to touchless sensors, which do not need direct contact. Their application in textiles ranges from the field of medical environments to smart home applications and the automotive industry. In this paper, a textile capacitive touchless sensor has been developed by using screen-printing technology. Two different designs were developed to obtain the best configuration, obtaining good results in both cases. Finally, as a real application, a complete solution of the sensor with wireless communications is presented to be used as an interface for a mobile phone.The work presented is funded by the Conselleria d'Economia Sostenible, Sectors Productius i Treball, through IVACE (Instituto Valenciano de Competitividad Empresarial) and cofounded by ERDF funding from the EU.

Dielectric and optical evaluation of high-emissivity coatings for temperature measurements in microwave applications

In this work, several commercial high-emissivity coatings have been characterized in terms of emissivity, chemical composition and dielectric properties as a function of temperature, under microwave irradiation. Accurate knowledge of their response under exposure to microwaves provides new and crucial information about their practical usability for non-contact temperature measurements in microwave environments. Due to their high metallic content, some of the studied coatings exhibited unexpected microwave-triggered reactions that hindered their use up to the maximum temperature specified by the manufacturers. Emissivity and chemical analyses before and after the heating cycles confirmed the degradation of some of the samples predicted by dielectric measurements. This work illustrates how a careful characterization of optical and dielectric properties under representative operating conditions (temperature range, microwave exposure) is vital in order to select the appropriate reference coating to obtain reliable temperature measurements in microwave applications

The first time on the other side: PhD candidates experience in digital electronics practical sessions and final project

[EN] The university Lecturer Training Fellowship granted by the Spanish Ministry of Education implies the participation of the PhD candidates in the practical lessons of subjects related to their specialty. For the first time, two students were assigned to the high performance group in Digital Electronics in the Industrial Electronics and Automation degree, taught in the School of Design Engineering (ETSID) of the Universitat Politècnica de València (UPV). Taking advantage of the PhD candidates¿ easiness for comprehending the student¿s point of view, they were allowed to suggest and implement methodological modifications with the aim of improving the knowledge and skill transfer in the subject field. The main result was the development of a methodology which relates the practical and theoretical parts so they are interleaved, making it easier to comprehend, assimilate the concepts, and participate actively in the practical part gaining experience in the field. The subject is divided in three main parts: VHDL, microcontrollers and a final project. One of the PhD students was assigned to the VHDL part, the other one to the microcontroller part, and the final project was collaborative, with both participating in the organization and evaluation. This final project evaluates the innovation, creativity and entrepreneurship transversal skills of the students by entrusting them to develop a microcontroller code and to write the documentation about it, while participating in a car-like robot competition. This year, the competition was presented as a list of requirements the robots must meet before the deadline to access the ¿final test¿, in a way that was first implemented by the successful aerospace company SpaceX for the international Hyperloop Pod Competition series. This makes the deadlines and evaluation items very clear for both students and evaluators while leaving the door open to different ways of implementation using the knowledge acquired through the semester. This paper presents the thought process behind the methodology used during the subject and final project and the results obtained, alongside with the experience reported by both students and PhD intraining candidates.Terrés-Haro, JM.; Monreal-Trigo, J.; Ibáñez Civera, FJ.; Gil Sánchez, L.; Garcia-Breijo, E.; Laguarda-Miro, N.

Redesigning seminars in the subject sustainable development and environmental ethics for the new on-line higher education scenario due to COVID-19

[EN] Covid-19 has changed the global agenda this year 2020 and particularly since March when the disease disseminated and affected the whole world. Then, confinement strategies started in most of the countries affecting important humankind aspects such as economy, society, and many others. In an educational point of view, higher education has been suddenly forced to change from a traditional presential education structure to a non-presential learning-teaching framework based on virtual/on-line educational strategies. Particular efforts have been done at the Universitat Politècnica de València (UPV) and in its Design Engineering School (ETSID) to adapt their educational model to this unexpected situation. This paper shows the work conducted to redesign seminars in the subject Sustainable Development and Environmental Ethics according to the requirements of this new scenario. A preliminary SWOT analysis allowed to focus our redesigning efforts in specific aspects of the seminar: assuming the nonpresential scenario and adapting to this new reality, an appropriate and more effective information sharing, some visual aspects associated to the specific teamworking dynamics in the classroom, structure and seminar schedule were some of the aspects to be on in the redesigning process. Students¿ opinions and point of view were particularly considered in redesigning as they are intensively experiencing on-line education since confinement started. Finally, structure, tasks, schedule, attendance, results compilation and sharing, and assessment were completely reconsidered and adapted. After this season¿s experience, development, results and students¿ feedback have been studied in depth. As a conclusion, the new redesigned seminar rises as a successful improved version of the activity being more dynamic, participative, and educationally functional. Although, there are important aspects that have been lost because they are linked to presential attendance and real teamworking in the classroom. Further efforts will be focused in diminishing these disadvantages.Laguarda-Miro, N.; Ibáñez Civera, FJ.; Gil Sánchez, L.; Garcia-Breijo, E.; Monreal-Trigo, J.; Terrés-Haro, JM. (2021).

Design of a low-cost equipment for optical hyperthermia

[EN] A laser equipment is presented which has been specifically designed for optical hyperthermia. Such specificity in the design has allowed implementation at costs significantly lower than other options currently available in the market. The developed equipment includes a 808 nm laser whose output power is up to 500 mW. It also incorporates additional devices that help the user in calibrating the system and supervising it while functioning. The performance of a prototype is tested by running two hyperthermia experiments: one involving gold nanorods, and the other using gold nanostars. The specific set-up of this prototype has allowed laser irradiation with radiated power densities up to 4W/cm(2). (C) 2016 Elsevier B.V.

In Situ Monitoring of Microwave Processing of Materials at High Temperatures through Dielectric Properties Measurement

[EN] Microwave-assisted processes have recognized advantages over more conventional heating techniques. However, the effects on the materials¿ microstructure are still a matter of study, due to the complexity of the interaction between microwaves and matter, especially at high temperatures. Recently developed advanced microwave instrumentation allows the study of high temperature microwave heating processes in a way that was not possible before. In this paper, different materials and thermal processes induced by microwaves have been studied through the in situ characterization of their dielectric properties with temperature. This knowledge is crucial in several aspects: to analyze the effects of the microwave field on the reaction pathways; to design and optimize microwave-assisted processes, and to predict the behavior of materials leading to repeatable and reliable heating processes, etc.García Baños, B.; Catalá Civera, JM.; Peñaranda Foix, FL.; Plaza González, PJ.; Llorens Vallés, G.

Atopic dermatitis incidence and risk factors in young adults in Castellon (Spain): A prospective cohort study

Introduction: There are few atopic dermatitis (AD) incidence cohort studies in young adults, the etiology of this disease remains obscure, and AD risk factors in adults are not well understood. The objective of this study was to estimate AD ten-year incidence and prevalence in a cohort of adolescent aged 14–16 at inception in Castellon province in Valencia Region, Spain and describe related risk factors. Material and methods: From 2002 to 2012, a population-based prospective cohort study was carried out. Questionnaires from the International Study of Asthma and Allergies in Childhood (ISAAC) were used with an additional questionnaire for related factors completed by participants and their parents, respectively, in 2002. In 2012 the same questionnaires were completed by the participants’ through a telephone interview, and incidence and prevalence of AD were estimated. Directed acyclic graphs, Poisson regression and inverse probability weighted regression adjustment were used. Results: The participation rate was 79.5% (1435/1805) with AD lifetime prevalence of 34.9% and AD incidence of 13.5 per 1000 person years. Females presented higher prevalence and incidence than males. After adjustment significant risk factors were being female, history of asthma or allergic rhinitis, family history of AD, history of respiratory infections, history of bronchitis, history of pneumonia, history of sinusitis, and birthplace outside Castellon province. The highest AD population attributable risks were female, 30.3%, and history of respiratory infections 15.3%. Differences with AD childhood risk factors were found. Conclusions: AD incidence in our cohort was high and several risks factors were related to AD

Diagnosis, management, and outcomes of patients with syncope and bundle branch block

Although patients with syncope and bundle branch block (BBB) are at high risk of developing atrio-ventricular block, syncope may be due to other aetiologies. We performed a prospective, observational study of the clinical outcomes of patients with syncope and BBB following a systematic diagnostic approach. Patients with ≥1 syncope in the last 6 months, with QRS duration ≥120 ms, were prospectively studied following a three-phase diagnostic strategy: Phase I, initial evaluation; Phase II, electrophysiological study (EPS); and Phase III, insertion of an implantable loop recorder (ILR). Overall, 323 patients (left ventricular ejection fraction 56 ± 12%) were studied. The aetiological diagnosis was established in 267 (82.7%) patients (102 at initial evaluation, 113 upon EPS, and 52 upon ILR) with the following aetiologies: bradyarrhythmia (202), carotid sinus syndrome (20), ventricular tachycardia (18), neurally mediated (9), orthostatic hypotension (4), drug-induced (3), secondary to cardiopulmonary disease (2), supraventricular tachycardia (1), bradycardia-tachycardia (1), and non-arrhythmic (7). A pacemaker was implanted in 220 (68.1%), an implantable cardioverter defibrillator in 19 (5.8%), and radiofrequency catheter ablation was performed in 3 patients. Twenty patients (6%) had died at an average follow-up of 19.2 ± 8.2 months. In patients with syncope, BBB, and mean left ventricular ejection fraction of 56 ± 12%, a systematic diagnostic approach achieves a high rate of aetiological diagnosis and allows to select specific treatment
