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 ...

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, ...

How researchers are modifying basic materials to enhance and tailor transducer performance. Efforts and results achieved with piezoelectric materials. Efforts and results achieved with triboelectric ...

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

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 ...

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

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.
