Materials can be considered the interface of a product as they mediate between user, environment and object (Karana, Pedgley and Rognoli 2014). They characterize the physical world and generate a continuous flow of sensory interactions. In this age of mass production, engineers and designers are in a unique position to use the opportunities presented by materials development and apply them in creative ways to trigger meaningful user experiences.
Dynamism is considered a very promising material experience in terms of creating meaningful interactions, and, consequently, user attachment to a product (Rognoli, Ferrara and Arquilla 2016). Dynamic products are those that show sensory features that change over time in a proactive and reversible way, activating one or more user’s sensory modalities and aiming at enhancing the user’s experience (Colombo 2016).
Smart materials could be considered the most suitable candidates to provide dynamic experiences. They react to external stimuli, such as pressure, temperature or the electric field, changing properties such as shape or colour. They are capable of both sensing and responding to the environment, as well as exerting active control of their responses (Addington and Schodek 2004). Compared to understanding traditional materials, smart materials involve additional technical complexity.
The aim of this paper is to share how the Material Driven Design (MDD) method (Karana et al. 2015) has been applied and to analyse a set of 10 projects, grouped into 5 case studies, developed by students from ELISAVA over the last 3 years to improve ways to implement the method. We have analysed the case studies in terms of the changes observed in the sensory features, using a sensory map proposed by Sara Colombo (Colombo 2016). By comparing different projects, the paper shows how the sensorial aspects are invoked by different smart material properties.
The 5 case studies have integrated the smart materials into functional prototypes for different application sectors, such as healthcare, energy harvesting or fashion. We have found that only three sensory modalities (sound, sight and touch) were involved in the user experience, with sight being the most predominant sensory perception.
This study aims to serve as a springboard for other scholars interested in designing dynamic products with smart materials.
