Paper Transistor

First transistors built using paper as a structural and electrical component

2 min read

29 August 2008—Researchers from Universidade Nova de Lisboa, in Portugal, say they’ve made a transistor in which paper acts as a functional component. Elvira Fortunato, who led the research, says that paper-based transistors will be orders of magnitude cheaper and could be used for low-cost, flexible, and disposable microelectronics, such as biosensors, intelligent packaging, and lightbulbs.

Compared with equivalent transistors using the same class of semiconductor but built on silicon dioxide, ”the performances are similar,” Fortunato says.

Why Functional Programming Should Be the Future of Software Development

It’s hard to learn, but your code will produce fewer nasty surprises

You’d expectthe longest and most costly phase in the lifecycle of a software product to be the initial development of the system, when all those great features are first imagined and then created. In fact, the hardest part comes later, during the maintenance phase. That’s when programmers pay the price for the shortcuts they took during development.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
