Manufacturing Rotational Mechanisms with Integrated Sensors

Integrating sensors into rotational mechanisms could make it possible for engineers to build smart hinges that know when a door has been opened, or gears inside a motor that tell a mechanic how fast they are rotating. Engineers have now developed a way to easily integrate sensors into these types of mechanisms.
