By solving the system with the values of piezoelectric outputs, current to be measured can be derived. Results of experiments of passive sensing are presented, proving the validity of the proposed ...

It is clear that a system with a piezoelectric actuator and sensor in the position xa = 0.0 m and length la = 0.7 m is the best choice, but with a piezoelectric actuator and sensor in the position and ...

A new sandwich-style triboelectric nanogenerator improves smart flooring by harvesting motion-based energy, even in wet ...

Vibration energy harvesting with piezoelectric materials is of practical interest because of the demand for wireless sensing devices and low-power portable electronics without external power supply.

To address this, we developed a smart glove embedded with a flexible piezoelectric nanogenerator (FPENG) for real-time, self-powered Morse code transmission via finger movements. The FPENG utilizes a ...

Jun 18, 2025 Selenium-doped nanoparticles improve fungicide delivery and trigger plant immunity Selenium-doped nanoparticles improve fungicide retention, activate plant defenses, and lower toxicity in ...

Among the main problems affecting the sound pressure level (SPL) of piezoelectric microelectromechanical systems (MEMS) speakers is that the membrane vibration displacement of those with sealed ...

In this work, antimony (Sb 3+) doping in lead-free perovskite NCs has been carried out to boost the nanogenerator performance of pristine PVDF material. Cs 3 Bi 2–x Sb x Br 9 @PVDF (x = 0.05) resulted ...

The recipe blends sodium alginate (an inert polymer extracted from brown seaweed) with thin titanium-carbide “MXene” nanosheets, then freeze-dries the slurry into an airy block about the weight of ...
