I've long wondered if there's a possible application for something like this using 3d printing and electrets. Basically you can freeze an electric field inside of an insulator if you apply it as the material solidifies. I think you should be able to embed electrets inside of 3d prints simply by generating a strong electric field at the print head or slightly behind it. You can also vary the field and embed a 3d electret that can act as, say, a sensor or a hidden ID in the print.
- Geee 2y agoSounds interesting! Maybe you should try to make this.
- calmbonsai 2y agoHuh? No you can't due to leakage inductance. Are you simply making a joke about permanent magnets?
- 01100011 2y agoHow does leakage inductance relate to electrets?
- calmbonsai 2y agoIn the exact same manner that leakage capacitance limits the field strength of permanent magnets--only more so by orders of magnitude. This is, fundamentally, why electrostatic motors have not seen "power" applications. It's far easier to manufacture a high-tolerance lattice in metals than non-metals. https://ieeexplore.ieee.org/document/1038668 https://ieeexplore.ieee.org/document/1038668
