Piezoelectric and triboelectric tactile sensors are designed to convert mechanical stimuli into electrical signals, making them critical components in intelligent systems. Piezoelectric sensors ...

Sensors used to monitor extreme environments need to provide reliable measurements despite high temperatures and harsh conditions. Now, researchers have developed a piezoelectric sensor that works at ...

This article explains some of the principles of signal conditioning. Piezoelectric sensors have been chosen to illustrate these principles because their conditioning requires a mix of traditional ...

For example, a 2-kN force properly applied to a cubic-centimetersized quartz crystal produces over 12.5 kV. Voltage created by an applied stress is called piezoelectricity. Unlike strain gages that ...

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, ...

Designing with piezoelectric sensors might seem, at first glance, a bit trivial but make no mistake, there are certain pitfalls of which to be aware as well as diverse configurations and internal ...

A research team has developed a machine learning-based acoustic sensor for speaker recognition. The team fabricated a flexible piezoelectric membrane by mimicking the basilar membrane in the human ...

(Nanowerk News) Researchers in China have demonstrated a high performance flexible piezoelectric nanogenerator (PENG) based on a piezoelectrically enhanced nanocomposite micropillar array of BaTiO3 ...
