These Tiny Power Converters Run on Vibrational Energy
Scientists at the University of California San Diego and CEA-Leti have developed a ground-breaking piezoelectric-based DC-DC converter that unifies all power switches onto a single chip to increase power density. This new power topology, which extends beyond existing topologies, blends the advantages of piezoelectric converters with capacitive-based DC-DC converters.
New compound that withstands extreme heat and electricity could lead to next-generation energy storage devices
Society’s growing demand for high-voltage electrical technologies—including pulsed power systems, cars and electrified aircraft, and renewable energy applications—requires a new generation of capacitors that store and deliver large amounts of energy under intense thermal and electrical conditions. Researchers at Lawrence Berkeley National Laboratory and Scripps Research have now developed a new polymer-based device that efficiently handles record amounts of energy while withstanding extreme temperatures and electric fields.
New Ultrathin Capacitor Could Enable Energy-Efficient Microchips
Scientists at Berkeley Lab and UC Berkeley have developed a thin film from a century-old material for next-gen memory and logic devices. The breakthrough advances the pursuit of low-voltage electronics that require less energy to operate than today’s silicon-based electronics.
Tulane scientist leads study on faster charging energy storage
A Tulane University researcher has led a team in discoveries that could result in significantly faster charging electric vehicles and portable devices such as cell phones and laptops.
Engineered defects in crystalline material boosts electrical performance
Researchers have discovered that engineering one-dimensional line defects into certain materials can increase their electrical performance.
Charges Cascading Along a Molecular Chain
Removing one charged molecule from a one-dimensional array causes the others to alternately turn ‘on’ or ‘off,’ paving the way for information transfer in tiny circuits
Toward an Ultrahigh Energy Density Capacitor
Researchers at Berkeley Lab and UC Berkeley have demonstrated that a common material can be processed into a top-performing energy storage material. Their discovery could improve the efficiency, reliability, and robustness of personal electronics, wearable technologies, and car audio systems.
