Materials can be considered from a technical and experiential perspective. However, the latter perspective is more complex to study systematically. Four intertwined experiential levels describe the overall materials experience: sensorial, interpretive, affective, and performative level. Building upon the need in experiential material characterization for comparable physical material representations to enable within-material-class comparisons and the inclusion of extensive user aspects, this paper sums up the reasoning process regarding the understanding and design of an experimental set-up and its parameters of a specific case. The case objective is to formulate guidelines for the designer/researcher to set up experiential material characterization experiments with (i) plastic demonstrator forms and (ii) by consumers. Following elements are discussed: Assessors, Stimuli, Interaction Modalities, Dependent variables, Method, and Practical considerations. Next, future experiments can be carried out in order to generate holistic plastic material data on a larger scale, that can be collected in an experiential database and used by designers throughout the design process.

The current COVID-19 pandemic has resulted in an immense and unforeseen increase in demand for personal protective equipment (PPE) for healthcare workers worldwide. Amongst other products, respirator masks are crucial to protect the users against transmission of the virus. Decontamination and reuse of the existing stock could be a solution to the shortage of new respirators. Based upon existing studies, it was found that (I) a solid quality control method is essential to test product reuse, (II) in-depth evaluation of the different parts of the filtering facepiece respirator (FFR) should be considered, and (III) communication of the reuse cycle is essential to take track of the amount of reuse, as this is limited to ensure quality. The goal of this paper is two-fold. First, we identify the impact of decontamination on the different parts of the FFRs and how the quality control should be performed. Two different types of FFRs are analysed within this paper, resulting in the recommendation of combining quantitative respirator mask fit testing with a thorough sensory evaluation of decontaminated FFRs to qualify them for reuse. Secondly, the possibilities of communication of this reuse to the eventual user are mapped through in-depth reasoning.

As designing with recycled materials is becoming indispensable in the context of a circular economy, we argue that understanding how recycled plastics are perceived by stakeholders involved in the front end of the design process, is essential to achieve successful application in practice, beyond the current concept of surrogates according to industry. Based on existing frameworks, 34 experiential scales with semantic opposites were used to evaluate samples of three exemplary recycled plastics by two main industrial stakeholders: 30 material engineers and 30 designers. We describe four analyses: (i) defining experiential material characteristics, (ii) significant differences between the materials, (iii) level of agreement of respondents, and (iv) similarities and differences between designers and engineers. We conclude that the three materials have different perceptual profiles or identities that can initiate future idea generation for high-quality applications. The study illustrates the potential of this evaluation method. We propose that designers can facilitate the valorization and adoption of these undervalued recycled materials, first by industry and ultimately by consumers as well.

Driven by the competitive market that product designers face today, a growing interest emerges in exploring experiential material qualities to enhance product experience. The maturing of the research area calls for standardization to evolve to more streamlined and systematic approaches to conduct characterization experiments. To this aim, we conducted a literature review on 64 cases of experiential characterization studies in the materials and design domain. In this paper, we summarize the current state of the art, formulate an overview to facilitate systematic studies to explore experiential qualities of materials, and identify gaps or opportunities for further research. The presented learnings shed light on the following aspects used in materials experience studies: (i) variables, (ii) stimuli, (iii) interaction modalities, (iv) experimental set-up, (v) methods employed in the conducted studies, and (vi) respondents. Two important gaps were identified with regard to the physical material representations in an abstract form as a critical element for multimodal material characterization experiments, and to an integration of extensive user aspects beyond demographic variables to facilitate consumer segmentation. Additional future research suggestions were formulated, concerning within-material-class comparisons, complementary methods and experimental set-up, and the temporality of materials experience.

With today’s continued drive to increase recycling rates of plastics, the low-hanging fruit of clean mono-streams of plastic waste has long since been picked. If Europe’s ambitious recycling targets are to be met, plastics waste streams that have until now been labeled ‘problematic’ and have consistently been sent to incineration, must be considered as well. One such stream is the sink fraction obtained from float-sink sorting of mixed post-consumer packaging waste. It is a very complex stream in terms of composition. Moreover, it contains a sizeable amount of PVC, which is considered detrimental to further mechanical recycling of any mixed plastic waste. Within the current research, the sink fraction was extensively analyzed for composition and mechanical properties, as well as treated for removal of PVC and non-ferrous metals. Subsequently, the Design from Recycling strategy was applied to successfully develop a new product with this material, called the Greentile. The Greentile was effectively manufactured and found to be a useful construction element for slanted green roofs.

Plastics are ubiquitous in our daily life due to their versatile characteristics, however, these excellent characteristics also contributed to the emergence of a gigantic garbage of floating plastics in our ocean, called the plastic soup. Within this research project we investigated the opportunities by design to cope with this wicked problem. The hypothesis is that picking small opportunities in a wicked problem can have a large impact on the related ecosystem. In addition, we also wanted to investigate how design students would deal with the problem to create larger awareness of the designers' impact and responsibility. Although there is no ideal answer to a systemic problem such as the plastic soup, intervening on systems is possible. As the characteristics of a product directly influence the way the entire value chain works, designers have a large responsibility / opportunity to influence the system. An experiment was executed with 69 design students to explore the opportunities. The resulting design concepts were discussed by experts, reasoning towards relationships, needs to elaborate the design practices, and ecodesign education in a circular economy.

Materials experience in design involves the meanings that materials convey to users through its expressive characteristics. Such meaning evoking patterns are influenced by parameters such as context, product (e.g.shape) and user. Consequently, there is a need to standardise experiential material characterisation and large-scale data collection, by means of a meaning-less or ‘neutral’ demonstrator to objectively compare materials.This paper explores the conception of this neutrality and proposes two opposing strategies: neutrality through complexity or through simplicity. In a pre-study with 20 designers, six associative pairs are selected as neutrality criteria, and shaped in 240 forms by 20 (non) designers in a main workshop. Following the simplicity strategy, these forms are averaged out in three steps by a team of five designers, based on a consensus on of delicate-rugged, aggressive-calm, futuristic-calm, masculine-feminine, traditional-modern, and toylike-professional, resulting in a selection of four averaged neutral forms.Finally, future research will focus on complexity to increase interactivity, so that consumers might be triggered in extensive material exploration.

In industrial design, materials selection plays an important role. Being the interface of a product, a material does not only have to meet technical-functional requirements, but also has to include intended experiential characteristics. Unfortunately, there is no one-to-one correspondence between materials and their expressive value, since a material’s perceived character is influenced by multiple contextual factors that are product-related (shape, function), user-related (gender, culture, etc.), and context-related (time, place, etc.). Our current research aims to explore possible relationships between materials, their expressive value and the link with self-expression of the end-user. It defines expressive value in terms of Schwartz end values. Consequently, this paper reveals insight in the expressive values that twelve pre-selected materials evoke in itself and in interaction with different pre-selected forms. Moreover, respondents are classified in meaningful self-expressive categories, based on their value orientation. For each of these segments, the materials and form-material combinations were investigated, both indirectly and directly, in relation to the fit between the expressive value of the material and the self-expression. Relationships were found between the self-perception and a material’s fit with the self-expression, and between materials and their perceived expression of values.

Keratitis, or an inflammation of the cornea, is a common eye disease in which a biopsy of the cornea is required to determine its underlying cause. Currently, no standardized tool is available for this purpose and corneal scrapings are performed with a scalpel or wide needle, frequently with inconclusive results as too little material is removed for fear of penetration. Previous research resulted in a new cutting principle, and is used in this follow-up study. The aim of this research is to optimize the usability of the cutting principle through a user evaluation (N = 18) of four ergonomic handle prototypes. The results of this study suggest that a forceps-shaped handle provides improved usability, and propose design guidelines for further optimization.

This paper presents a detailed case study on the effective upcycling of a post‐industrial plastic waste stream to a renewed compound, fit for re‐use in a new application. The material investigated was a PET‐contaminated recycled PP, destined for a high‐impact, medium‐stiffness application. After two research trials and one large‐scale industrial trial, an upcycling formulation was determined to bring the recyclate to the required level of the new application, thus closing this specific material loop within the case company. The used methodology adheres to the Design from Recycling principle, in which industrially available (mechanically) recycled polymer materials are matched to potential new products. The design strategy starts from either the properties of an available recycled polymer (and then defines the product) or from the functional boundary conditions of the product (and then selects the material and/or an optional material upcycling step). The Design from Recycling principles can elegantly be combined with those of Design for Recycling, within the framework of a Circular Economy. POLYM. ENG.

Keratitis is a common eye disease where a biopsy is required to determine the underlying cause of the inflammation of the cornea. Currently, no standardized tool is available for this purpose and corneal scrapings are performed with a scalpel or wide needle, frequently with inconclusive results as too little material is removed for fear of penetration. Consequently, biopsies are rarely performed and a broad-spectrum antibiotic is prescribed, which may result in untoward sequelae. This study investigated the usefulness of a skin punch tool to obtain corneal biopsies as compared to a regular scalpel. The punch tool was more accurate to reach the objective biopsy radius of 2 mm. Additionally, biopsy duration was about half (88.4 s) when using the punch tool as compared to the use of the scalpel (162.4 s). This research shows a verification method that can be used to evaluate corneal biopsy tools.
