Physicists have proposed turning piezoelectric crystals, the same materials found in quartz watches and microphone pickups, into detectors for axion dark matter. The idea, called the piezoaxionic ...

Dark matter, a type of matter that does not emit, reflect or absorb light, is predicted to account for most of the matter in ...

Researchers at the Chinese Academy of Sciences have produced ultrathin bismuth ferrite (BiFeO₃) films that deliver a fourfold ...

Albuquerque, N.M. — For the past three years a Sandia research team headed by Mat Celina has been investigating the performance of various piezoelectric polymer films that might one day serve as ultra ...

The tactile device is thin, flexible, and has 25 stimulation generating points within a 2 cm × 2 cm area. To achieve wearable, to install the driving circuit close to the device, we use high voltage ...

Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, ...

The word “piezo” derives from the Greek word piezein, meaning “to press tightly”. Piezoelectricity refers to a material’s ability to convert mechanical energy (pressing) into electric energy ...
