Abstract
Wearable technology and product sustainability in the apparel industry is an increased focus of consumers. A major problem of wearable electronics currently on the market is the reliance on conventional power supplies (i.e. batteries) that are typically heavy, made from topic sources, and have a short lifetime. To save resources, solar energy can be harnessed. Flexible solar panels offer a sustainable, lightweight source of energy, but consumer attitudes towards solar powered clothing are greatly affected by the product's functional, expressive, and aesthetic (FEA) qualities (Hwang, Chung, & Sanders, 2016; Lamb & Kallal, 1992). Because few apparel products beyond accessories exist in the marketplace today, research is needed on the functionality of solar panels and their integration into apparel in an expressive and aesthetic manner. Therefore, the purpose of this study was to collaborate with an interdisciplinary research team to design a solar powered jacket that focuses on prosperity, people and the planet using the FEA model and apparel design framework (Lamb & Kallal, 1992). Through problem identification, preliminary ideas, design refinement, prototype development, evaluation and implementation, much was learned about consumer preferences and how to balance them with functional needs of electronic components, while also maintaining focus on environmental friendliness.
