A team of Indian scientists have developed a transparent triboelectric nanogenerator device.
About Triboelectric Nanogenerator(TENG)?
- A triboelectric nanogenerator(TENG) is a self-powered device that makes use of mechanical energy in the form of vibrations present everywhere in different forms to generate electricity.
- Working:
- It works on the principle of creation of electrostatic charges via instantaneous physical contact of two dissimilar materials followed by generation of potential difference when a mismatch is introduced between the two contacted surfaces through a mechanical force.
- This mechanism drives the electrons to move back and forth between the conducting films coated on the back of the tribo layers.
- Technique used: The device was developed using the simpler doctor’s blade technique along with polyethylene terephthalate(PET) as tribo layers.
- Doctor’s blade technique is one of the widely used techniques for producing thin films on large area surfaces.
- Significance: The device could light up 11 LEDs by gentle hand tapping and could be a potential candidate for use in optoelectronics, self-powered devices and other biomedical applications.
- Optoelectronics is the field of technology concerned with electronic device application to the sourcing, detection and control of light.
