Jesse Sullivan, a Tennessee power company lineman whose arms were amputated after he was electrocuted on the job, now has artificial limbs that let him rotate his wrists and upper arms, bend his elbow, grip with his hand, and, incredibly, feel. Sullivan's arm employs nerves from the chest muscle. When that muscle contracts, a myoelectric sensor atop his skin detects the contraction and sends it to an amplifier and then to a digital signal processor (DSP) in the Boston Digital Arm. The arm’s DSP interprets the signal and then sends a command to the hand motor, which closes the hand. (Source: Liberating Technologies)
I remember when I first graduated college in the early 80's nearly all of my peers were taking jobs with major defense contractors.The joke was, mechanical engineers made weapons.Civil Engineers make Targets.I really didn't like that joke and vowed to always work in industrieswhere technology advancements improve the human condition.After 30-some years, I admit I have spent some time in military contract work, but medical, automotive and communication have been my career.Seeing these latest prosthetics validates my earliest career choice.The Mechatronics interrelationship with human physiology and nervous system was once just a dream now being realized. Absolutely fantastic stuff.
Wow, what a great slide show, Chuck and what an impressive lineup of technology. I'm particularly struck by how far prosthesis have come with technical advances like robotics and sensors enabling the device to mimic real human movement and to tie into the nerves for natural dexerity. Amazing what engineers are accomplishing.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
At the recent Consumer Electronics Show in Las Vegas, 3,600 exhibitors demoed new products, most of which used sensors. Accelerometers, magnetometers, gyroscopes, cameras, touch screens, infrared and radar sensors endowed products with the ability to see, hear, and feel.
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.
