Last week, MIT researchers published a blog post highlighting a paper detailing work on fully 3D printable electronics — namely a simple, semiconductor-free logic gate. The original paper was written by Jorge Cañada, a grad student in electrical engineering and computer science, and Luis Fernando Velásquez-García, a principal research scientist in MIT's Microsystems Technology Laboratories.
Logic gates can be used for undemanding workloads including controlling the speed of a motor, and MIT researchers have proven that for such simple electronics, usage of 3D printing and a biodegradable copper-doped polymer can forego the need for semiconductors at such a small scale.
