The classic sparkling wine that has rung in countless new years with a bang may have more to its bubbles. Champagne is notable for its iconic cork popping, but the bubble acoustics also play a key role in determining how ...
Wind turbines have a design life of 20 years. The rotor blades must be regularly inspected at least once every four years to verify their structural integrity. This type of work is performed by industrial climbers. But the ...
(Â鶹ÒùÔº)—The piezoelectric effect, which causes a material to expand along the direction of an applied electric field, is common in many materials and used in a variety of technologies, from medical ultrasound to vibration-powered ...
An advance in fabrication technology has greatly improved the material quality and performance of thin films of a lead-free 'piezoelectric' material. This development by A*STAR researchers promises to unlock a lead-free alternative ...
Researchers from Empa have developed a flexible material that generates electricity when stressed. In future, it might be used as a sensor, integrated into clothing or even implanted in the human body, for instance, to power ...
Researchers at Kanazawa University and the University of Tokyo report in Nature Communications the visualization of the dynamics of 'molecular scissors'—the main mechanism of the CRISPR-Cas9 genetic-engineering technique.
One of the elements modern diesel engines require to become energy-efficient and clean are precisely controllable injection nozzles using piezo crystals. How exactly these crystals work has not been fully understood to date. ...
Piezoelectric materials are used for applications ranging from the spark igniter in barbeque grills to the transducers needed by medical ultrasound imaging. Thin-film piezoelectrics, with dimensions on the scale of micrometers ...
Through the combined effect of flexoelectricity and piezoelectricity, researchers at the ICN2 led by ICREA Gustau Catalán in collaboration with the UAB have found that polar materials can be made more or less resistant to ...
Researchers at MIT and Brigham and Women's Hospital have built a flexible sensor that can be rolled up and swallowed. Upon ingestion, the sensor adheres to the stomach wall or intestinal lining, where it can measure the rhythmic ...
