The research in energy efficient and sustainable technologies for buildings is currently an important issue because of their high‐energy consumption. In this regard, VO2–based thermochromic windows are showing promising results in terms of their energy savings ability. However, no previous study has investigated their lifecycle environmental impact...

Recognition of texture properties requires sliding contact between finger and object surface. Although it is well known that vibrations stimulate the tactile afferents, the mechanism by which Friction-Induced Vibrations (FIVs) interfere with tactile perception is still unknown. As well, the role of mechanical stimuli on hedonistic feedback from the...

Considering object identification and recognition as well as human interaction with objects, texture as a surface property plays a crucial role. A deeper understanding of tactile aesthetics can be useful in the applied field such as in product designs that appeal more to our senses and that are more effective in eliciting certain emotional response...

Materials teaching is part of a paradigm shift currently happening in the design education. It has become crucial to provide design students with an up-to-date knowledge about the latest advance in materials and manufacturing technologies with the aim to prepare them to more effectively cope with the next industry challenges. The introduction of sm...

Teaching “calm technology” and “smart materials” as prospective trends in product design is the motivation of the educational workshop presented in this paper. Materials can trigger creative thinking. Indeed, concepts can be generated ideas that come from the encounter with a material showing the material's unexpressed potential. However, a smart m...

The shift from linear to circular patterns is on the way and rise many questions. In the last ten years, reuse and upcycling are gaining more attention. Since reduce and reuse were describe as a priority by the European Union, some leading projects are unveiled in different countries. Scale and quality of those projects push the reuse issue out of...

VO2 has been intensively studied as a model system for metal‐insulator transition (MIT), ever since its phase switching behavior at relatively low temperature (Tc = 68 °C) was discovered. Its thermo‐active characteristics have been studied for applications in thermal solar collectors to prevent overheating of the fluid absorber, smart windows, and...

The sliding contact between the finger and the surface of an object generates vibrations that propagate into the skin and activate the mechanoreceptors. The characteristics of the vibrating signals give information about the texture features, affecting the tactile perception. Previous studies have focused on the relation between the physical charac...

What makes designs intuitive? One essential part of it has to do with perception. The human body retrieves and processes information about its immediate surroundings at two levels: physical and perceptual. From the material engineer point of view, when a person interacts with a product, he (or she) interacts with the product and the materials simul...

The tactile perception of a surface texture is mediated by factors such as material, topography and vibrations induced by the sliding contact. In this paper, sensory characterizations are developed together with topographical and tribo-tactile characterizations to relate perceived features with objective measurements of tribological and dynamic sig...

Ce travail de recherche a pour objet la prospection de différentes approches topographique, tribologique et sensorielle afin de mieux comprendre les mécanismes de perception tactile. En effet, lors du balayage d'une surface par le doigt, les mécanorécepteurs situés à la pulpe du doigt agissent comme des transducteurs qui convertissent les stimuli m...

Sensory attractive products can generate a strong user-product relationship. Many things can influence the user perception such as prize, colour, texture, etc. This last attribute can determine the acceptance of a product, and can be perceived through different sensory modalities. Manufacturer can benefit from learning more about the effect of thei...

Selection and definition of materials surfaces in product design can be driven by the sensory effect conceived. Certain characteristics that can be perceived through the sense of vision can also be perceived through the sense of touch. As a consequence, the sense of touch also plays an important role in functional user-product interactions. In this...

The main problematic of the research is to connect the stimuli-responsive behaviour of functional material to the end-user experience. To make this connection, the research was divided in layers, from the most technical at the bottom, to the most designerly at the top. The objective is to propose a set of chained tools that will eventually allow a...

Functional materials, also called “smart materials”, are materials that can “sense environment events, process that sensory information and then act on the environment” [1]. These materials are able to transform a given stimulus into a response. We use the general term “transition phenomenon” to account for the diversity of the underlying physical...

This review article describes recent advances in the elaboration of graphene-based colloidal nanocomposites through the use of graphene or graphene oxide in heterophase polymerization systems. Two main routes are reviewed: latex blending and in situ polymerization. In the first strategy, a segregated network is formed by confining the graphenic fil...

Anodizing of aluminum generates a nanoporous alumina layer comprising cylindrical nanopores extending essentially perpendicular to the substrate. Visual observation of such nanoporous layers shows a colored specular reflectance consistent with reflectance spectrum measurements. Such structural colors raise interest in particular for producing non-f...

Definition Stimuli-responsive materials (SRMs) have the particularity to change one or more of their properties under a defined stimulus. To account for the variety of underlying physico-chemical mechanisms, we call " transition phenomenon " the process by which SRMs transform an input, or stimulus, into an output, or response. For designers, this...

Anodizing of aluminum generates a porous alumina layer comprising cylindrical nanopores (300 nm diameter) extending essentially perpendicular to the substrate. The pore distribution over the surface exhibits a short-distance order close to hexagonal arrangement. On the contrary, long-distance order cannot be defined: the arrangement is not periodic...

Surface finishes based on structural colors raise interest in product design and architecture in that long lasting colored surfaces can be produced with low risks if color fading. In this paper, aluminum surface are patterned through anodization with additional chemical post-treatment. This electrochemical technique is advantageous in that it is al...

Le design se pratique en projet de conception d’objets. Le plus souvent, ce n’est pas le seul métier ou la seule discipline à intervenir. Dans tout projet de conception / design, l’utilisation et la manipulation d’information sont vitales. Le support de l’information doit accompagner le dialogue entre les métiers. Si le dessin technique permet l’éc...

Conductive composites based on few layer graphene are of primary interests. In this work latex based composites were produced leading to a specific cellular morphology. Highly conductive graphene-based composite materials have been produced through a solvent-free procedure. Both the mechanical and conductivity behaviors were successfully described...

We investigate the gonioapparent character of colored anodized titanium surfaces. In appropriate experimental conditions, the anodizing process generates a homogeneous oxide layer at the surface of the metal, with a thickness comparable with the visible wavelengths of light. The anodized metallic surfaces thus exhibit interferential colors, which d...

Smart materials are materials that change properties according to stimuli, adapting to their environment. This makes them particularly interesting, to increase the performance of a product, and to enable new functionalities and new ways to interact with users. Some smart materials can affect the perception we have of objects. Existing smart materia...

The analysis of users' experience is indispensable in order to catch the subjectivity. For this reason the industrial designer needs to take into account these new qualitative properties, and translate them in a concrete way during the creative process. Firstly the sensory information acquired need to be coached by the material experience. The user...

Gonio-apparent surfaces, characterized by large variations in optical properties with small variations in detection or illuminating directions, have a huge appeal for industrial product for aesthetic reasons. This work is dedicated to the design of a gonio-spectrophotometer (OptiMines goniometer) adequate for analyzing the light reflecting behavior...

Holistic approach for intelligent innovation is obtained in integrated design teams by mixing up backgrounds and skills into multidiscipline teams. However, is mixing enough? To go further than a simple addition of skills and create a synergy, the key ingredient is to favour communication and understanding between individuals in the team. Our aim i...

a b s t r a c t This review intends to present different aspects concerning clay/polymer nanocomposites produced by heterophase polymerization in aqueous media. This paper highlights the ability of miniemulsion poly-merization to produce clay/polymer nanoparticles with tailored nanostructures. Indeed, this polymeri-zation route enables the synthesi...

This article is devoted to the effects of the presence of modified clays during in-situ polymerization. Such synthesis routes require clay modifications in order to render the clay surface compatible with the monomer-polymer and/or reactive during polymerization. In addition, the use of nanometric clays (laponite) induces a large surface area which...

Among other uses, latexes are a successful alternative to solvent-borne binders for coatings. Efforts are made to produce hybrid nanostructured latexes containing an acrylic phase and an alkyd phase. However, after the film-forming process, the surfactant used to stabilize these latexes remains in the film, and its location can have a drastic effec...
