Implantable micro-devices may one day help regenerate nerves in humans, but for now they are limited by several factors. One limitation is the processing methods used for making the micro-devices, which sometimes require etching patterns into the biodegradable materials. Shoachen Chen is helping medical equipment designers develop micro-devices by improving the processing of biodegradable materials. The Iowa State University professor of industrial and manufacturing systems engineering uses lasers for producing micro-features on polymer surfaces. He is carving out answers to questions about how lasers remove materials from polymers. His work, funded by the National Science Foundation, is important to understanding how designers integrate materials into biodegradable micro-devices.

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
