Compiled after three years of dedicated and ongoing research by expert analysts, this report details IDTechExs coverage of the wearable technology ecosystem. The report looks at the industry from many different perspectives, with detailed discussion framing core primary research and market forecasting. The reports looks at the historical context for wearable technology products, looking at key yet contrasting sectors such as medical devices and commodity infotainment items like headphones or electronic watches. It then focuses on key trends today, ranging from societal megatrends (e.g. the aging population), to industry-wide innovation trends (e.g. evolving form factors and interfaces in devices), and finally down to core player-by-player strategies within industry and product verticals.Fuelled by a frenzy of hype, funding and global interest, wearable technology was catapulted to the top of the agenda for companies spanning the entire value chain and world. This investment manifested in hundreds of new products and extensive tailored R&D investigating relevant technology areas. However, the fickle nature of hype is beginning to show, and many companies are now progressing beyond discussing wearables to focus on the detailed and varied sub-sectors. Within this report, we include sections on each of these key product areas, including fitness trackers, smartwatches, smart clothing, smart eyewear (including AR and VR), smart skin patches, headphones and more. We also look separately by application sector (including healthcare & medical, fitness & wellness, professional sports, infotainment, enterprise, military and fashion), giving detailed case studies within each, but also discussing the trend that is seeing increasing cross-industry collaboration and product development.
