image: Design and fabrication of flexible capacitive humidity sensors. (a) Fabrication processes of flexible Ga2O3/LM humidity sensors, including ultrasonication, spraying coating and laser sintering.

Capacitive displacement sensor’s touch-free nature makes it ideal for fragile surfaces and high-speed machinery.

Researchers created a system that enables makers to incorporate sensors directly into rotational mechanisms with only one pass in a 3D printer. This gives rotational mechanisms like gearboxes the ...

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 ...
