ferroelectric or piezoelectric properties. Examples of materials for devices are polymers, oxides, semiconductors and liquid crystals. A microlithography technique can be used to create pixelated ...

Composite and lead-free materials – new from PI ... as well as in power ultrasonic applications for example with Langevin ...

The charge distribution in piezoelectric materials is inherently asymmetric. When exposed to mechanical stress, for example, bending, this asymmetry is increased, resulting in charge separation ...
