3D-printed gearboxes are always an interesting design challenge, especially if you want to make them compact. [ZeroBacklash] created a little strain wave gearbox (harmonic drive) for when you want to ...

3D printers are good for a lot of things, but making parts for power transmission doesn’t seem to be one of them. Oh sure, some light-duty gears and timing belt sprockets will work just fine when ...

Engineering researchers have developed a prototype of a high-performance flexible lithium-ion battery that demonstrates -- concurrently -- both good flexibility and high energy density. The battery is ...

Researchers from Columbia University have developed a prototype for a flexible battery based on the shape of the human spine, and it has properties similar to non-flexible batteries. Share on Facebook ...
