Power/Performance Bits: June 8


High temp capacitor Researchers at Pennsylvania State University doped a dielectric capacitor to increase storage capacity while also increasing electric charge efficiency, enabling the capacitor to withstand greater voltage with very little energy loss at temperatures higher than 300 degrees Fahrenheit. “What we have done is to use interface effects in nano-dopants to increase both the stor... » read more

Scaling Battery Technology


Batteries are an essential ingredient for the growth of electronics from small devices used for IoT as well as large batteries for electric cars. Historically, battery energy density improves 5%-8% per year. While this is much slower than the historical improvements from Moore’s Law, it’s still the kind of growth that can result in leaps in efficiency, opening the door for a better experien... » read more

Power/Performance Bits: Sept. 3


Nylon capacitor Researchers at the Max Planck Institute for Polymer Research, Johannes Gutenberg University of Mainz, and Lodz University of Technology developed a way to fabricate ferroelectric nylon thin-film capacitors. Nylons consist of a long chain of polymers and, along with use in textiles, exhibit ferroelectric properties. However, electronic applications have been limited as there ... » read more

System Bits: July 10


Light waves run on silicon-based chips Researchers at the University of Sydney’s Nano Institute and Singapore University of Technology and Design collaborated on manipulating light waves on silicon-based microchips to keep coherent data as it travels thousands of miles on fiber-optic cables. Such waves—whether a tsunami or a photonic packet of information—are known as solitons. The... » read more

PowerDown: Power Efficiency


Power Down Semiconductor wants to make the batteries in smartphones and IoT devices last 10 times longer by not wasting power they’ve already used. Every time an intelligent device has a thought, it pulls power from a battery and sends it through its maze of wires and millions of gates to create a O or a 1 at key points in the control and logic circuits. “Think about how much energy... » read more

Neuromorphic Computing: Modeling The Brain


Can you tell the difference between a pedestrian and a bicycle? How about between a skunk and a black and white cat? Or between your neighbor’s dog and a colt or fawn? Of course you can, and you probably can do that without much conscious thought. Humans are very good at interpreting the world around them, both visually and through other sensory input. Computers are not. Though their sheer... » read more

Manufacturing Bits: Sept. 23


The annual IEEE International Electron Devices Meeting (IEDM) will take place in San Francisco from Dec. 15-17. As usual, there will be presentations on the latest technologies in a number of fields, such as semiconductors, bio‐sensors, energy harvesting, power devices, sensors, magnetics, spintronics, two-dimensional electronics, among others. Here’s just some of the papers that will be pr... » read more
