(Invited) scavenging of Mechanical Energy Using Piezoelectric and Triboelectric Materials

Abstract

The issue of the research for self-powered nanosystems is likely to integrate different nano-devices into a stand-alone. Such nanosystem, surely, requires a sustainable power source to make the entire package as self-powered one. In this regard, scavenging energy from the environmental sources can be a possible choice for powering nano-systems. Among the others, there are many of mechanical form of energy (such as body movement, muscle stretching) or vibration energy (such as acoustic/ultrasonic wave) which can be converted into electric energy. In here, we have demonstrated some approaches for converting mechanical energy into electric energy by piezoelectric, ferroelectric nanomaterials and triboelectric nanostructures. The technology allowed us to harvest energy which is mostly regarded as wasted mechanical movement/vibration or noises. Moreover, new design of devices have been fabricated, and possible materials for such generators have been explored. The presentation will be continuously dedicated to recent developments and improvements of energy harvesting technology towards self-powered nano-systems.
