Self-powered sensors based on nanogenerators

Our ability to scavenge and convert ambient energy into electricity offers an unprecedented opportunity for powering various electronics systems and sensors, and to build an integrated system capable of battery-free operations. Triboelectric nanogenerators that use triboelectrification and electrostatic induction to recover electrical energy from mechanical vibrations have been proved as a new way to generate electricity. Piezoelectronic nanogenerators have also attracted rising interests in the past decade. The integration of the triboelectric nanogenerators/piezoelectronic nanogenerators and energy storage units gives the opportunity for making various types of self-powered sensors for application in electronics, bio-sensors, nanorobotics, biomedical sensors, etc.

Scope:
