The Limits Of Energy Harvesting


Energy harvesting, once considered an inexpensive alternative to low-power design and a way of achieving nearly unlimited power in mobile devices, has settled down to more modest expectations. This approach to generating energy through a variety of means—from solar to motion to ambient RF and even pH differences between soil and trees—has been proven to work. The problem is that it doesn... » read more

Energy At The Edge


Ever since the first mention of the IoT, everyone assumed there would be billions of highly efficient battery-powered devices that drew milliwatts of energy. As it turns out, we are about to head down a rather different path. The enormous amount of data that will be gathered by sensors everywhere cannot possibly be sent to the cloud for processing. The existing infrastructure cannot handle i... » read more

Tech Talk: Near-Threshold Power


Lauri Koskinen, CTO and founder of Minima Processor, and Ron Moore, vice president of marketing at ARM, talk about near-threshold computing, dynamic power and margining, and how these techniques can extend battery life and reduce energy consumption. https://youtu.be/BhiNFe4NYQU » read more

New Materials For Computing


The U.S. Department of Energy rolled out a new program to develop materials for "extreme conditions" for high-performance computing, setting the stage for much more mobile versions of AI and machine learning. This effort, if successful, has interesting implications on a number of levels. For one, the DOE's mandate includes everything from energy security to weaponry, and high-performance com... » read more

Sustainability Saves Water, Too


After energy (discussed in Part 2 of this series), water is the largest fab input and the largest contributor to fab waste. Yet tools for analyzing a fab’s water footprint are generally less mature than tools for analyzing emissions of CO2 and other greenhouse gases. In part, this may be because water consumption is primarily a local issue, while greenhouse gas emissions are a global c... » read more

OLEDs Shine In Phones, TVs, Lights


OLEDs are coming—everywhere. While the new iPhone 7 models do not have organic light-emitting diode (OLED) displays, those handsets are likely to be the last Apple will offer before it makes the smartphone transition to OLED displays next year. The Apple Watch, however, does have a flexible OLED display with a sapphire crystal cover or an Ion-X glass cover, and the Apple Watch Series 2 ... » read more

Breakthrough Energy Innovation: Ambition And Urgency


The easy answers to developing products for more sustainable energy designs have already been found, so only the toughest challenges remain to be solved. Innovative improvements to existing products are leading to increased complexity, while disruptive developments push engineers into uncharted design spaces. Either path — increased complexity or unknown territory — requires greater design ... » read more

Power Estimation: Early Warning System Or False Alarm?


Semiconductor Engineering sat down with a large panel of experts to discuss the state of power estimation and to find out if the current levels of accuracy are sufficient to being able to make informed decisions. Panelists included: Leah Schuth, director of technical marketing in the physical design group at [getentity id="22186" comment="ARM"]; Vic Kularni, senior vice president and general ma... » read more

Power/Performance Bits: Feb. 10


Solar power technology progresses at a snappy pace and the diversity of approaches keeps expanding. In this edition, investigations in two aspects of solar energy design: understanding a potential solar cell material and a design to make those we use now more effective. Unravelling the peculiarities of nanocrystals Researchers at ETH Zurich conducted an extensive study of nanocrystal ... » read more
