Abstract: In this paper, a piezoelectric micromechanical ultrasonic transducer (PMUT) featuring a "double-circle-ear" cavity structure is proposed on the basis of a circle cavity structure to improve ...

The efficiency of a solar panel is heavily dependent on having a clear and clean surface. But over time, dust and dirt buildup can block light and reduce their electricity output. Regular washing can ...

One of the reasons gold is so valuable is because it is highly unreactive—if you make something out of gold, it keeps its lustrous radiance. Even when you can react it with another material, it’s also ...

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, ...

Piezoelectric resonators (PRs) have been used to store energy in vibrational mode instead of electric mode by exploiting the underlying piezoelectric effect. Increasing power density and reducing the ...

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 ...
