Physicians get the credit for saving lives, but the behind-the-scenes work of engineers improves the lives of countless people in hospitals across the country every day.
Bionic limbs, innovative infusion systems, and transcranial doppler brain scanners are just some of the innovations engineers are bringing to the exploding medical design arena.

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.
Could our view of distant galaxies be obstructed by a lawnmower? That unlikely question is at the heart of a growing debate between the National Radio Astronomy Observatory and a robot manufacturer that seeks to build self-guided lawnmowers.
Design News readers spoke loudly and clearly after our recent news story about a resurgence in manufacturing -- and manufacturing jobs. Commenters doubted the manufacturers, describing them as H-1B visa promoters, corporate crybabies, and clowns. They argued that US manufacturers aren’t willing to train workers, preferring instead to import cheap labor from abroad.
Using wireless chips and accessories, engineers can now extract data from the unlikeliest of places -- pumps, motors, bridges, conveyors, refineries, cooling towers, parking garages, down-hole drills and just about anything else that can benefit from monitoring.
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.
