A “Half &Half” drive step with half amplitude and half resonance period kills overshoot and ringing of piezoelectric ...

Introduction Piezoelectric devices leverage the piezoelectric effect, where certain materials, such as quartz and ceramics, produce an e ...

Piezoelectric actuators offer high-speed response, fine resolution, and low power consumption. Piezoelectric crystals can be used to harvest ambient mechanical energy, such as vibrations or motion, ...

Piezoelectric energy harvesters do exist and they can produce usable quantities of power, but to do so they must be distorted slightly, or bent. They are best suited to harvesting energy from ...

This simple STM setup utilises a piezoelectric actuator constructed by deliberately cutting a piezo speaker into four quadrants. With individual drive wires attached to the four quadrants.

Piezoelectric drivers and piezoelectric amplifiers are power sources that provide the high voltage levels needed to drive other piezoelectric devices such as actuators, motors, transducers, and ...

A piezoelectric accelerometer is widely used for OEM applications and is suitable for working at a lower power consumption and wider frequency range. Piezoelectric force sensors are low impedance ...

Hearing loss is irreversible and the most common work-related injury worldwide. Prevention is the only way to tackle this ...

The team has much bigger goals than lighting up shoes or bike helmets, though. Researchers develop innovative shoe material that can generate electricity with every step: 'We are excited and ...
