Transistors that wrap around tissues and morph with them

Transistors that wrap around tissues and morph with them | Pahndeepah Perceptions | Scoop.it

Electronic devices that become soft when implanted inside the body and can deploy to grip 3-D objects, such as large tissues, nerves and blood vessels have been created by researchers from The University of Texas at Dallas and the University of Tokyo.

 

These biologically adaptive, flexible transistors might one day help doctors learn more about what is happening inside the body, and also could be used to stimulate the body for treatments.

 

The research, published in Advanced Materials, is one of the first demonstrations of transistors that can change shape and maintain their electronic properties after they are implanted in the body, said Jonathan Reeder, a graduate student in materials science and engineering and lead author of the work.

 

“Scientists and physicians have been trying to put electronics in the body for a while now, but one of the problems is that the stiffness of common electronics is not compatible with biological tissue,” he said.

 

“You need the device to be stiff at room temperature so the surgeon can implant the device, but soft and flexible enough to wrap around 3-D objects so the body can behave exactly as it would without the device. By putting electronics on shape-changing and softening polymers, we can do just that.”

 

Shape memory polymers (plastics) developed by Dr. Walter Voit, assistant professor of materials science and engineering and mechanical engineering and an author of the paper, are key to enabling the technology.

 

The polymers respond to the body’s environment and become less rigid when they’re implanted. In addition to the polymers, the electronic devices are built with layers that include thin, flexible electronic foils first characterized by a group including Reeder in work published last year in Nature.

 

The Voit and Reeder team from the Advanced Polymer Research Lab in the Erik Jonsson School of Engineering and Computer Science fabricated the devices with an organic semiconductor but used adapted techniques normally applied to create silicon electronics that could reduce the cost of the devices.


“We used a new technique in our field to essentially laminate and cure the shape memory polymers on top of the transistors,” said Voit, who is also a member of the Texas Biomedical Device Center. “In our device design, we are getting closer to the size and stiffness of precision biologic structures, but have a long way to go to match nature’s amazing complexity, function and organization.”

The Back Road (Jungian Psychology in Everyday Life Series) | Dr. Jeff Howlin | Pahndeepah Perceptions | Scoop.it
Keith Wayne Brown's insight:

When we talk about going on a road trip and taking back roads, we are generally hoping to see the details of a land and people or region. We hope to find a good surprise. Maybe we also hope that the feeling of the passage of time will slow down a bit. To allow for seeing these details and playing with perceptions of time, we want to avoid the common road or thoroughfare that the masses drive upon. The back road is the road that passes through the mountain peaks and valleys, the deserts and prairies, and the forests and swamps. As any traveler knows, the back road is also more likely to contain the unknown, hidden gems. Jungian psychotherapy is a lot like taking the back roads.

5 Ways Social Media Is Changing Your Brain | IFLScience | Pahndeepah Perceptions | Scoop.it
The persistence of social media is certainly changing how things are done. In a matter of minutes, you can wish an old friend happy birthday on Facebook, find a recipe for dinner on Pinterest, watch a how-to project on YouTube, and get up to the minute updates on events from Twitter. But social media isn’t just changing how we act; it’s actually changing our brains as well.

As much as the movies and technology are helping the industry, however, even more credit should go to comic book creators. Most comics are simply better these days — and that's my personal opinion, but it's also a popular one. Comics books have become far more sophisticated since their debut last century. Contemporary mainstream comics can be excellent, while creative alternative comics are more plentiful than ever.
