Scientists have illuminated the basic mechanism of Piezo proteins, which function as sensors in the body for mechanical stimuli such as touch, bladder fullness, and blood pressure. The discovery is a ...

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.

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 ...

New bismuth-based piezoelectric rivals lead ceramics, enabling greener sensors, wearables and self-powered electronics.

(Nanowerk News) The flip side of the convenience that electronic devices brings us, electronic waste presents a complex and growing challenge on the path toward a circular economy – a more sustainable ...

How do piezoelectric accelerometers — vibration sensors — work? The force caused by vibration or a change in motion (acceleration) causes the sensor's mass to “squeeze” contained piezoelectric ...

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 ...
