Eric J Wilhelm'sResearch
|I am developing an additive microfabrication technique based
on liquid embossing nanoparticle colloids. The potential applications include
truly 3-dimensional MEMS and logic, biological scaffolding, and photonic band
gaps. I hope to one day make a desktop sized machine able to produce
everything that currently requires a billion-dollar ultra-clean silicon microfabrication
