Printed circuit board motors replace wire windings with copper traces and report about 7% higher efficiency, helping cut ...
Conductive filament exists, but it takes more than that to 3D print something like a circuit board. The main issue is that traces made from conductive filament are basically resistors; they don’t act ...
A green printed circuit board (PCB) has been developed using cheap, abundant fibres extracted from banana and sisal plants 1, which could replace plastic and glass-fibre materials commonly used in ...
