Using a speculative design foresight approach, this study explores the rapidly developing area of wearable, implantable and ingestible technologies, and how they might influence us over the next several decades. The authors have combined traditional research methods such as literature review and expert interviews; foresight methods, such as environmental scanning, trends analysis and scenario creation; and narrative, imagery and conjecture to produce an evocative account of future possibilities in the realm of the tools we keep and use close to and inside our bodies.
