Plastic electronics could lead to electronic wallpaper, energy-generating windows and medical patches that deliver medicine on demand, Princeton researchers say.
Now, a new video describes how these plastics could be used: for electronics.
Compared to silicon, "plastic electronics" are lightweight, low-cost (compared to, for example, the indium tin oxide used in solar panels) and can change shape easily.
Researchers think plastic electronics could give rise to electronic wallpaper, windows that generate energy (by absorbing the sun's rays), inexpensive solar panels and patches that deliver medicine when you need it most.
To make this a reality, researchers need to mass-produce plastic transistors, not unlike your home printer prints on a piece of paper.
"Conductive polymers [plastics] have been around for a long time, but processing them to make something useful degraded their ability to conduct electricity," said Yueh-Lin Loo, a chemical engineering professor at Princeton, at the time.
The problem with moldable plastic electronics was that they would lose conductivity as they were shaped. But the Princeton researchers developed a new technique in which they relaxed the structure of the plastics by treating them with an acid after they were processed.
The result: a plastic transistor, made by quite simply printing the plastic onto a surface. That's significant because expensive, specific machines would no longer be needed to manufacture the electronic parts.
The use cases for such plastics are many: as diagnostic tools and sensors, they could change colors to indicate change, such as if a patient is sick. As solar cells, they would be quickly and efficiently manufactured. And the technique could lend itself to improved TV and computer displays, too.
According to a IDTechEx research report, the market for printed and thin film electronics will be $1.92 billion this year -- about 43 percent of that for OLED displays. But by 2020, the market will grow to $55.1 billion.
Plastic electronics wouldn't entirely replace traditional electronics, of course -- but in key situations, they would ensure faster, cheaper, smarter production.

Where are the details and what is so novel? Lamination and impregnation has been part of electronic tech since its origins. Trying to wade through this rather muddled report for some definite novelty fails to provide much that enlightens but shows that many such applications already exist. Was this a novel approach with circuits laminated upon malleable materials; or an inclusive device using plastic materials treated to have semi-conductive qualities integrated with substrate and the associated layers? What about the power requirements and circuit protection abilities? Does the approach require less petroleum ingredients? Can production involve recycled materials? I've referred to the links but those mostly are commercial information services. Could the content include more research and organization while using less vacuous buzzwords please?
Cool idea, somewhat predicted by Cory Doctrow and his 3D printer themes. In that thought exercise, 3D printers that also can print electronics become ubiquitous in homes and businesses and can make most the things we buy these days. If this tech works as hoped, and if it ends up being generally printable, it would be a very interesting, disruptive technology. Your home printer may be printing your next cell phone...
Every time a new semiconductive device appears, it reacts a little differently to audio signals. I'm very curious to see what new variables a plastic transistor or diode may bring to the table in terms of sounds for guitar and bass players.
