The idea that technologies influence society—both positively and negatively—is not new. This is mainly the terrain of the philosophy and the ethics of technolo-gy research. Similarly, design research aims to help create new technologies in line with individual, social, and societal needs and values. Against this backdrop, it seems essential to expose relations between design and philosophy of tech-nology research, particularly from a methodological perspective. The main goal of this paper is to suggest a preliminary overview of methods and approaches that can inspire and inform interdisciplinary collaboration and, with that, sys-tematic engagement with ethics in design processes. Through interdisciplinary exchange, we propose a preliminary typology of ethics-informed methods and approaches based on two main dimensions, namely theory-grounded approaches to theoretically-flexible techniques and assessment to accompaniment. This mapping intends to help navigate the ethical qualities of selected methods from both disciplines, and it aims to create a platform for fruitful interdisciplinary conversations.

Methods for Sensing and Monitoring Fatigue Cracks and Their Applicability for Marine Structures

In order to guarantee structural integrity of marine structures in an effective way, operators of these structures seek an affordable, simple and robust system for monitoring detected cracks. Such systems are not yet available and the authors took a challenge to research a possibility of developing such a system. The paper describes the initial research steps made. In the first place, this includes reviewing conventional and recent methods for sensing and monitoring fatigue cracks and discussing their applicability for marine structures. A special attention is given to the promising but still developing new sensing techniques. In the second place, wireless network systems are reviewed because they form an attractive component of the desired system. The authors conclude that it is feasible to develop the monitoring system for detected cracks in marine structures and elaborate on implications of availability of such a system on risk based inspections and structural health monitoring systems

Gas sensing performance at room temperature of nanogap interdigitated electrodes for detection of acetone at low concentration

From the article: "A facile approach for the fabrication of large-scale interdigitated nanogap electrodes (nanogap IDEs) with a controllable gap was demonstrated with conventional micro-fabrication technology to develop chemocapacitors for gas sensing applications. In this work, interdigitated nanogap electrodes (nanogap IDEs) with gaps from 50–250 nm have been designed and processed at full wafer-scale. These nanogap IDEs were then coated with poly(4-vinyl phenol) as a sensitive layer to form gas sensors for acetone detection at low concentrations. These acetone sensors showed excellent sensing performance with a dynamic range from 1000 ppm to 10 ppm of acetone at room temperature and the observed results are compared with conventional interdigitated microelectrodes according to our previous work. Sensitivity and reproducibility of devices are discussed in detail. Our approach of fabrication of nanogap IDEs together with a simple coating method to apply the sensing layer opens up possibilities to create various nanogap devices in a cost-effective manner for gas sensing applications"

Nature areas in North-West Europe (NWE) face an increasing number of visitors (intensified by COVID-19) resulting in an increased pressure on nature, negative environmental impacts, higher management costs, and nuisance for local residents and visitors. The high share of car use exaggerates these impacts, including peak pressures. Furthermore, the almost exclusive access by car excludes disadvantaged people, specifically those without access to a car. At the same time, the urbanised character of NWE, its dense public transport network, well-developed tourism & recreation sector, and presence of shared mobility providers offers ample opportunities for more sustainable tourism. Thus, MONA will stimulate sustainable tourism in and around nature areas in NWE which benefits nature, the environment, visitors, and the local economy. MONA will do so by encouraging a modal shift through facilitating sustainableThe pan-European Innovation Action, funded under the Horizon Europe Framework Programme, aims to promote innovative governance processes ,and help public authorities in shaping their climate mitigation and adaptation policies. To achieve this aim, the GREENGAGE project will leverage citizens’ participation and equip them with innovative digital solutions that will transform citizen’s engagement and cities’ effectiveness in delivering the European Green Deal objectives for carbon neutral cities.Focusing on mobility, air quality and healthy living, citizens will be inspired to observe and co-create their cities by sensing their urban environments. The aim to complement, validate, and enrich information in authoritative data held by the public administrations and public agencies. This will be facilitated by engaging with citizens to co-create green initiatives and to develop Citizen Observatories. In GREENGAGE, Citizen Observatories will be a place where pilot cities will co-examine environmental issues integrating novel bottom-up process with top-down perspectives. This will provide the basis to co-create and co-design innovative solutions to monitor environmental problems at ground level with the help of citizens.With two interrelated project dimensions, the project aims to enhance intelligence applied to city decision-making processes and governance by engaging with citizen observations integrated with Copernicus, GEOSS, in-situ, and socio-economic intelligence, and by delivering innovative governance models based on novel toolboxes of decision-making methodologies and technologies. The envisioned citizens observatory campaigns will be deployed and fully demonstrated in 5 pilot engagements in selected European cities and regions including: Bristol (the United Kingdom), Copenhagen (Denmark), Turano / Gerace (Italy) and the region of Noord Brabant (the Netherlands). These innovation pilots aim to highlight the need for smart city governance by promoting citizen engagement, co-creation, gathering new data which will complement existing datasets and evidence-based decision and policymaking.

Sensing Streetscapes: co-researching emerging technologies for enhancing urban design

De woningbouwopgave is enorm. Alleen al in Amsterdam is de bouw van minimaal 50.000 woningen tot 2025 voorzien. De impact op onze steden is nauwelijks te overschatten. Met name doordat deze nieuwbouw binnenstedelijk en daardoor in extreem dichtheden en hoogbouw gerealiseerd moet worden. We weten dat voor een goede leefomgeving de straat een menselijke maat moet hebben. Voor de gangbare woonmilieus is bekend wat voor ontwerpoplossingen dit vraagt: een actieve plint (begane grond), ritme in de straatwanden en een tactiele inrichting. Voor de nieuwe woonmilieus met on-Nederlands hoge dichtheden en hoogbouw is nog niet duidelijk hoe dat moet gebeuren. Duidelijk is dat er aandacht nodig is op het sociale vlak, programmering, mobiliteit, en de vormgeving van de straatruimte als gezamenlijke publieke ruimte met een menselijke maat. Dit onderzoeksvoorstel richt zich op de straatruimte. Ruimtelijk ontwerpers hebben urgente behoefte aan een systematisch overzicht van (elders) beproefde ontwerpoplossingen, meer grip op de werking van deze ontwerpingrepen en een tool om ontwerpoplossingen al gedurende het ontwerpproces op hun werking te kunnen testen. Om in deze behoefte te voorzien, is een consortium gevormd bestaande uit ontwerpbureaus, (internationale) kennisinstellingen die de opgave op soortgelijke interdisciplinaire manier aanpakken en een groep opdrachtgevers van ruimtelijke projecten. Sensing Streetscapes past twee nieuwe opkomende technologieën toe (artificial intelligence uit data-analytics en de eye-tracking-technologie uit de neurologie) die nodig zijn om referentielocaties te traceren en het effect van ontwerpoplossingen op de gebruikers van de straatruimte te achterhalen. Naast de kennisontwikkeling worden de technologieën ook doorontwikkeld tot twee nieuwe tools voor de toepassing in de ontwerppraktijk. Ontwerpers kunnen daarmee zelf sneller referentielocaties traceren en ontwerpoplossingen zelf toetsen bij de gebruikers. Hiermee zijn de ontwerpers in staat om met beter beproefde oplossingen per situatie en locatie straatruimtes een herkenbare menselijke maat te geven en de ontwerppraktijk innoveert.

Wearable Photonics for Continuous Health Monitoring

The continuous monitoring of health indicators in biofluids such as sweat, saliva, blood, and urine has great potential for preventive medicine. Techniques that continuously monitor biomarkers still remain a major technological challenge. Recently, a concept of dynamic biosensing was published that is based on mediator particles. Such mediator particles exhibit rapid switching between a bound and unbound state during interaction with a probing structure to which they are connected through a molecular tether (like a balloon on a string). Although the concept of using mediator particles for dynamics biosensing is very promising, the used detection method is not a viable solution as it is not miniaturizable. We propose to use a photonic ring resonator (RR) or Mach-Zender interferometer (MZI) as the probing structure in combination with a highly miniaturizable readout scheme. In this project, we perform preliminary experiments to prove that this photonic approach can be used for the detection of the mediator particles tethered to the photonic waveguide. To bridge the gap with the practical application by health professionals, we will enrich the envisioned solution through OnePlanet's OpenEd program. OpenEd aims to share technology and innovations (e.g. prototypes) with educational institutes (MBO, HBO) that want to further innovate their courses or work methods, such that current and future professionals are well prepared to work with new (digital) technologies. By presenting our use-case as a 'challenge' to teachers, students and practitioners, OpenEd also allows enriching the use-case by involving (future) health professionals that can provide feedback on - or further investigation of - the practical application of our new technology from the health professional's perspective.
