A new research field, nanopiezotronics refers to
generation of electrical energy at nanometer scale
through mechanical stress to the nanopiezotronic
device. This is the new approach of the potential of
converting biological mechanical energy,
acoustic/ultrasonic vibration energy, and bio fluid
hydraulic energy into electricity, representing a new
way for self-powering of wireless nanodevices and
nanosystems. Nanopiezoelectronic devices include
nanowires, nanogenerators, sensors and transistors are
playing crucial role in nanoscience and biotechnology
as well as biomedical applications. The perspectives of
the potential applications of the silicon nanowires for
biodetection and drug delivery are very crucial to the
biomedical field. Thus, the concept of
“nanopiezoelectronics” is introduced as a set of
approaches to engineer the nanowires and nanodevices/
nanosensors and to enrich their functionality and
potential applications in nanoscience and biotechnology
for the upcoming future.
