System Bits: Feb. 26


Firefly microstructures in LED light bulbs Pennsylvania State University researchers wanted to improve the energy efficiency of commercial light-emitting diode light bulbs to save even more energy. They found the answer in the lantern surface of fireflies. "LED lightbulbs play a key role in clean energy," said Stuart (Shizhuo) Yin, professor of electrical engineering at Penn State. "Overall... » read more

System Bits: Jan. 29


Quantum physics make hybrid semiconductors glow Hybrid semiconducting materials have quantum properties capable of bringing significant changes to light-emitting diode lighting and monitors, along with photovoltaic solar cells, researchers at the Georgia Institute of Technology report. Physical chemists worked with halide organic-inorganic perovskite (HOIP), which combines a crystal lattice wi... » read more

A Longer Life For LED Power Electronics


One of the greater challenges with LED lighting is the electronic driver’s robustness to normally occurring transients or power surges in the network. Many everyday examples have shown that the active electronics in the light sources find it hard to handle the effects in a use environment, in which incandescent bulbs and lamps with passive electronics have functioned fine for decades. A new p... » read more

The Week in Review: IoT


Cybersecurity Arm this week introduced the Cortex-M35P processor with anti-tampering technology and software isolation. The company also debuted security intellectual property to protect Internet of Things devices from physical cyberattacks and close proximity side-channel attacks. Paul Williamson, Arm’s vice president and general manager of the IoT Device IP line of business, provides more ... » read more

Power/Performance Bits: Sept. 8


Solar water-splitting By splitting water molecules, Rice University researchers have demonstrated what they say is an efficient way to capture energy from the sun and convert it into clean, renewable energy. The technology relies on a configuration of light-activated gold nanoparticles that harvest sunlight and transfer solar energy to highly excited electrons, which scientists sometimes re... » read more
