A research team led by Igor Efimov at Washington University in St. Lewis has developed a stretchy, custom-fitted, implantable device that can give doctors feedback about life-threatening irregularities occurring inside someone’s heart. This photo shows sensors embedded in the silicon membrane that could provide stimulation to the surface of the heart. (Source: Washington University/St. Louis)
Excellent post Elizabeth. Several years ago my father, age 84 at that time, underwent emergency surgery for a heart valve replacement. He was a candidate due to his overall physical condition. Today he is 91 and probably has a stronger heart than I. Medical engineering and medical technology absolutely amaze me and the application of 3-D printing to these fascinating fields indicates what a marvelous place and future "addititive" manufacturing has. I really appreciate the information and had no idea engineers and doctors were working towards this type of preventative medicine.
You're welcome, Debera. I didn't know this technology was used for other applications, so it's good to know that now. And yes, the heart application is really fascinating and could do a lot to help people with chronic heart conditions in terms of quality of life, I think.
Thanks Elizebeth for such an interesting post , No doubt 3d technology is being used for a number of good and life saving purposes . I was just aware that this technology is being used in medical in terms of transpants of the organs and dentistry but ths smart membrane is really very innovative method of detecting heart problems.
This is an interesting follow-up to another story I wrote about heart-valve technology that flexes like a real heart valve: http://www.designnews.com/author.asp?section_id=1386&doc_id=272112
There is a lot of new innovation happening in the area of artificial heart technology and other technology to help people with heart problems, as well as technology to improve other artificial limbs. This one especially is really interesting, because it marks a possible breakthrough in treatment for people with chronic heart problems. I'd be curious to see what those in the medical field think about this.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
