To improve the communication between patients and bioelectronic devices, the interface between the two should follow the curve of the body. Researchers have developed a curvature-matching design strategy that can enhance wearability during skin motion.

Contact is Key to Bioelectronics

A combo of wireless sensors and computer models reveals bridge integrity issues unseen by conventional inspections.

Diagnosing Bridge Health

Engineers are finding a growing number of applications for mechanical metamaterials, which feature unique mechanical properties that are determined by their structure.

The horizontal-axis wind turbine has become an efficient and economical means to produce electricity. Some of the largest machines can produce as much as 15 MW when running at full capacity. But such turbines can be too complicated for small-scale operations or for capturing wind power in urban settings.&nbsp;

Space Manufacturing Could Need Acoustic Levitation 

When a ballistic shield is struck with a heavy object, it can actually bend backward toward the shield holder. Researchers want to know if these shields do enough to protect against arm injury.

How Well Do Shields Protect? 

Yes, says Bechel&rsquo;s John Gülen, but probably not in some of the carbon-neutral applications that have received attention over the past decade.
