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 ...

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 ...

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

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, ...

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

Fine tuning sensors on prosthetics includes incorporating the sense of touch into a device to be as close to the sensations felt by a natural limb as can be. The two began working together last ...

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.
