Developments In Piezoelectric Nanogenerators

Acceleration sensors play a crucial and essential role in many fields, such as large mechanical structure testing, national defense, transportation, auto industry, biomedical devices, and so on. Usually, a commercial acceleration sensor is made with piezoelectric ceramic, owing to its eminent piezoelectric performance (piezoelectricity can transform a force signal to an electrical signal). However, the application of piezoelectric ceramic acceleration sensors is largely limited in extreme service environments because of its inherent brittleness during performance. What’s more, the subsequent polarization...
