Medical technology has undergone some of the most revolutionary changes of any field in the Twentieth Century. And while many of the advances have included drugs, many more have involved the technology physicians use to diagnose and treat illness. Several winners of the Design News Engineer of the Year award have won for the medical-device breakthroughs they have brought about, including Rowland Redington (MRIs), Terry Haber (safe needles), Victor Poirier (left ventricular heart device), Dean Kamen (infusion pumps for dispensing drugs), and our most recent winner, Lynn Otten, who developed the first device to receive FDA approval for long-term implant in the brain. It controls essential tremors from Parkinson's Disease.
Here are some of the other medical breakthroughs of the century:
The first practical electrocardiograph, invented by Willem Einthoven in 1900.
The first X-ray patent, awarded to William Coolidge in 1917.
The electroencephalograph, 1929.
The first artificial kidney for humans, 1943.
The heart-lung machine, 1953.
The cardiac pacemaker, invented by Wilson Greatbach, 1958.
The laser, which enables present-day applications such as non-invasive retina surgery, cauterization of stomach ulcers, and the clearing away of cholesterol blockages of arteries.
Functional neuromuscular stimulation, 1961.
Fiberoptic endoscopes, to enable physicians to visually examine body cavities and hollow organs without invasive surgery, 1968.
Positron Emission Tomography, 1970.
Computer Axial Tomography, 1970.
Magnetic Resonance Imaging, 1979.
Lithotripsy, the ultrasonic technique for crushing kidney stones.
Functional Electrical Stimulation for grasp-and-release motor prosthesis.
The Jarvik artificial heart, 1982.
Cochlear implants, 1983.
The Parastep motor prosthesis system for limb control, 1995.
And many more. What others would you add to this admittedly partial list?
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
