A typical piezoelectric sensor comprises a disk of PZT-5A ceramic material with metallized electrodes on its surfaces. Applying electrically conductive epoxy to the electrodes connects external wiring ...

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 design was done to get a sealed keypad for very wet environments (in my particular case, showers for swimming pools). The keypad needed to be able to detect slight pressure on a stainless steel ...

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

A research team led by Dr. Lim Sang-kyu in DGIST's Department of Energy and Environmental Technology has developed a smart fiber sensor that can detect natural disasters such as landslides in real ...

Ultrasonic sensor transducers work well in medical applications such as patient monitoring, flow measurement and air bubble detection used in infusion systems, pharmaceutic devices or spirometry.

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

The piezoelectric effect is simple in its rules: Apply mechanical stress to a material and you generate an electric charge. The inverse is also true: Apply a voltage to a material, and it changes ...
