This onion chopper seems clever, with these intersecting cutting blades forming a grid mounted by a set of plastic hinges to a cutting board. Just swing the knife grid down and – voila! — chopped onions. Too bad the designers didn’t account for the fact that an onion is not isotropic. Depending on the orientation of the onion, some parts don’t get a clean cut. Or no cut at all, as was the case here when the plastic hinge broke under the force applied while attempting to cut axially into the leathery end slice of an onion.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
