TechCrunch:

The Amazon Robotics-designed product was created to keep workers safe when they need to enter a space in order to fix a robotic system or retrieve fallen items. Built-in sensors alert Amazon’s robotic systems to the wearer’s presence, and they slow down to avoid collision.

This seems both fascinating and inevitable.

Imagine a fast moving robot, rapidly shelving or retrieving product, or packing products into a shipping container. The robots move fast enough, their appendages flying from task to task, that a human coming near risks real injury. The slow motion vest triggers a sensor and the robot goes into a much slower, more predictable speed so the human can grab a dropped item or access a control on the robot itself. Fascinating.

As to inevitable, this seems like an idea that will spread to any space where humans and robots coexist. At least until detecting humans becomes second nature, and flawless, for robots.
