This document discusses the rise of smart hardware and wearable devices. It notes that cheaper sensors, increased computing power in smartphones, improved networking technologies, and crowdfunding have lowered barriers to entry for new devices. Examples are given of popular wearable devices for health monitoring and smart watches from companies in the US and China. Challenges and implications are discussed around syncing devices, real-time requirements, power sources, and paradigm shifts in app design and how data drives intelligence. Open questions are also raised about how wearables may change behavior and which devices will integrate the most functions.
