The Material Aesthetics Lab: Creating Interactive Experiences with MatterIssue: XXX.5 September - October 2023
Amy Winters, Bahar Barati, Anke van Oosterhout, Miguel Bruns
Imagine a world where the very materials and objects we interact with possess the ability to adapt and transform themselves, akin to being alive. Here, sensing, actuation, computation, and communication become increasingly interwoven into the novel ecologies of materials, artifacts, humans, and nonhumans that we live with, wear, and interact with (Figure 1). The Material Aesthetics Lab (www.materialaesthetics.com), in the Department of Industrial Design at Eindhoven University of Technology, works at the cross section of interaction design, biology, robotics, and materials science.

Clockwise from top left: The Algal Relay Computer (ARC) is a simple form of computer that incorporates the growth of micro-algae in its calculation process ; Shape-Changing Food Materials is a collaboration with two-Michelin-starred restaurant Alchemist on incorporating interactive materials into high-end dining ; Ripple Thermostat is a designerly exploration into how haptics and shape-change can mediate between humans and intelligent systems .|
We address human and more-than-human challenges by questioning design methods that have disconnected humans from nature , and exploring more expressive computational [1,2] and material systems . We aim to redefine interactivity by moving from a focus on efficiency and functionality toward a deeper inclusion of aesthetic and environmentally conscientious approaches. The transformative potential inherent in matter offers an experimental environment for exploring the aesthetics of interaction through soft robotics  (Figure 2), shape-changing interfaces  (Figure 1), and haptics  (Figure 1).

With a focus on the research themes of more-than-human temporalities, the materiality of care, inclusive gastronomy, sustainable soft robotics, and haptic experience design, we develop and investigate tools and methods through the design and cocreation of experience prototypes. Our researchers prioritize material-driven design methods  and frameworks that suggest the behaviors of phenomena in designing interactive matter. Our prototypes aim to engage diverse stakeholders in discussions and reflections about probable and preferable future applications of emerging materials in everyday life.
The Material Aesthetics Lab features a range of digital manufacturing equipment, with a diverse set of materials and fabrication processes, including multi-materials (Figure 3), bio-materials (Figure 4), clay (Figure 5), and 3D food printing (Figure 1). The lab is strategically located across from the electronics and mechanical engineering workshops of the department to facilitate collaboration between different disciplines. The lab has an open studio setup, enabling researchers, graduate students, technicians, as well as artists in residence from diverse backgrounds to support, inspire, and cross-pollinate each other.

Projects incorporate a wide range of materials into everyday artifacts; for example, blending the realms of biology, ecology, and economics and their temporalities in projects such as Algal Relay Computer (Figure 1), mycoSonic (Figure 4), and Multispecies Refuge 2050 (Figure 5). They aim to bridge the gaps between people in diverse professions—for example, chefs, experts in creating pleasurable food experiences, and material scientists, developers of more sustainable and healthier edible materials . Through our projects, we devise new tools for designers, such as rapid-prototyping approaches for actuators to improve accessibility and form-giving (Figure 2) , thereby illustrating how soft robotics present both a compelling opportunity and novel challenges for the design-HCI community. We also support haptic interaction design through soft- and hardware tools to rapidly sketch and prototype novel tactile and material experiences . We encourage hands-on experimentation to understand how making informs the design process and novel aesthetics; for example, chitosan-based actuators are biodegradable and have multiple functions (Figure 6). Our transdisciplinary approaches to fabrication unlock opportunities for the expressive and performative properties of materials, aiming to inspire researchers from mono-disciplinary STEM fields.

By taking materials, aesthetics, and making as our point of departure, the lab envisions shaping the design engineer of the future. We look forward to collaborating with researchers, artists, and industry and invite you to join the Material Aesthetics Lab launch at the Dutch Design Week, October 21–29, 2023 (https://ddw.nl/) in the Design United (https://www.4tu.nl/du/) and Drivers of Change (https://ddwtue.nl/) exhibitions.
