With few exceptions, power transmission is a field where wobbling is a bad thing. We generally want everything running straight and true, with gears and wheels perfectly perpendicular to their …read more Continue reading Bent Shaft Isn’t a Bad Thing for This Pericyclic Gearbox
Any project that contains something called a “flux modulator” instantly commands our attention. And while we’re pretty sure that [Retsetman] didn’t invent it after hitting his head on the toilet, …read more Continue reading Magnetic Gearbox Design Improvements Are Toothless but Still Cool
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 …read more Continue reading 3D Printed Strain-Wave Gearbox Turns Up the Torque
Outside of very small applications, Nikola Tesla’s ideas about transmitting serious power without wires have not been very practical. Sure, we can draw microwatts from radio signals in the air …read more Continue reading Wireless Power: Here? Now?
Like a lot of power transmission components, bearings have become far easier to source than they once were. It used to be hard to find exactly what you need, but …read more Continue reading Adding Wire Races Improves 3D-Printed Bearings
Arguably the biggest hurdle to implanted electronics is in the battery. A modern mobile phone can run for a day or two without a charge, but that only needs to fit into a pocket and were its battery to enter a dangerous state it can be quickly removed from the pocket. Implantable electronics are not so easy to toss on the floor. If the danger of explosion or poison isn’t enough, batteries for implantables and ingestibles are just too big.
Researchers at MIT are working on a new technology which could move the power source outside of the body and …read more
