Printed miniature loudspeaker listening into the future

In an additive manufacturing process, miniature loudspeakers can be produced efficiently and cost-effectively as part of piezoelectric microelectromechanical systems – so-called piezo-MEMS – using a combination of inkjet printing and…

Impurities boost performance of organic solar cells

Sunlight offers a potential solution in the search for an energy source that does not harm the planet, but this depends on finding a way to efficiently turn electromagnetic energy…

Supercapacitors challenge batteries

Graphene hybrid material reaches power density of batteries A team working with Roland Fischer, Professor of Inorganic and Metal-Organic Chemistry at the Technical University Munich (TUM) has developed a highly…

New class of cobalt-free cathodes could enhance energy density of next-gen lithium-ion batteries

Oak Ridge National Laboratory researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries that power electric…

Power boost thanks to gold lamellae

Research team develops new material system to convert and generate terahertz waves. On the electromagnetic spectrum, terahertz light is located between infrared radiation and microwaves. It holds enormous potential for…

‘Chaotic’ way to create insectlike gaits for robots

By using small networks of Rössler systems, a locomotion controller enables a brain-machine interface for a six-legged antlike robot. Researchers in Japan and Italy are embracing chaos and nonlinear physics…
