Implant electronics with silicon on silk
Implant anything large (that is, as large as a human hair) in the body and there will be problems such as irritation or outright rejection. However if you implant something very very small – nanoscale...

Kids these days are smart. Or at least they have more familiarity with electronics. Yesterday a boy and girl from the 2nd grade approached me after a science class. They looked very pleased with...
View ArticleGraphene: Diverse advances
Scientists thought they understood carbon, until nanotechnology came along. Working with carbon at the atomic level (the nanoscale) has revealed many surprising properties. In particular, graphene, a...

Graphene oxide memristors combine cheap and flexible
In electronics graphene is quickly becoming the great hope for replacing and improving upon silicon semiconductors. Since silicon semiconductors are the basis of much commercial electronics (especially...

The MIM diode: Another challenger for the electronics crown
Sometimes good ideas in technology languish because of serious implementation hurdles. The MIM diode (Metal-Insulator-Metal) was one of those technologies. Note the past tense.Essentially, a diode...

Graphene transistor: Two layers may be better than one
One of the characteristics of clever science is to look at a new material from every which way. So it is with graphene. Graphene is a sheet of carbon atoms, in a layer one atom thick, arranged in the...

Promising new material: Electronic and optically active photonic crystals
Although it’s not as tricky as producing new drugs for medicine, developing new materials for commercial electronics is usually no sure thing. There is a long path of testing and development between...

A new twist for graphene: Trying to solve the bandgap problem
Although it’s like a sheet of paper (if paper could be only one atom thick), but “Do not bend, fold, mutilate or spindle” does not apply to sheets of graphene. Scientists all over the world are doing...
