Nextreme Inc., a maker of micro-scale thermal and power management products in Research Triangle, NC, has developed a novel way to cool chips while banking energy. The company runs the cooling process in reverse, converting the heat into power circuitry that trickle-charges batteries. The process arises from an esoteric — yet basically simple — change in the way chips are packaged.
Nextreme's innovation creates a thermally active copper pillar bump. When electrical current is passed through the bump one side cools rapidly relative to the other and the bump actually generates power. While the principles behind the process have been known for a long time, they've only been possible thanks to recent advances in nanotechnology.
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.
