New perovskite-related material could find applications in sensors, wearables, and printed electronics ...

Piezoelectricity is a property of certain materials to become electrically polarized under strain and stress. This phenomenon has been studied extensively since it was first discovered in the mid-18 ...

Scientists have been focusing on the application of high dielectric constant capacitors, buzzers, sensors, ultrasonic motors, actuators, piezoelectric sonar, ultrasonic transducers, medical diagnostic ...

“Smart Materials” are materials that change their shape, color, or size in response to an externally applied stimulus. Examples of “external stimuli” include changes in temperature, application of an ...

“Hey, Cortana.” “Hey, Alexa.” “Hey, Lyra.” “Hey, Robin.” “Hey, Siri.” If you’ve ever owned a quartz watch, received an ultrasound exam in a doctor’s office, or enjoyed a voice-controlled personal ...

As a dense suspension of piezoelectric nanoparticles shear thickens due to a transition from frictionless (gray) to frictional (red) particle–particle interactions, friction-induced piezoelectricity ...

SAN JOSE, Calif.--(BUSINESS WIRE)--EMFIT, the Finnish company known for its electroactive ferroelectret sensors, sensor-integrated systems and the EMFIT QS quantified sleep monitor, expands into new ...

The piezoelectric effect refers to the negative and positive charges that appear on the surface of specific crystals when pressure is applied. This phenomenon was discovered by Pierre and Jacques ...

Piezoelectricity is a material’s capacity to transform mechanical energy (pressing) into electric energy (polarization) and vice versa. The word “piezo” derives from the Greek word piezein, which ...

Harvesting energy from the human body may sound scary, but fortunately a Matrix-style setup exists only as a cinematic fiction. Instead a typical path lies in external contraptions that use the body’s ...

The underlying mechanism improving piezoelectricity via interfacial polarization is elucidated through combining the experimental results, molecular dynamics simulations and density functional theory ...
