Context: Researchers at the Institute of Nano Science and Technology (INST), Mohali, under the Department of Science and Technology (DST), Government of India, have developed a triboelectric nanogenerator (TENG) using flexible single crystals of an organic compound.
About Triboelectric Nanogenerator (TENG)
- Triboelectric Nanogenerator (TENG) is a small device that generates electricity from movement or friction. It works on the triboelectric effect, which happens when two materials rub against each other and create an electric charge.
- Eg. When you rub a balloon on your hair, your hair sticks to it because of the electric charge. A TENG uses a similar principle but converts this charge into usable electricity.
Uses of TENG
- Energy Harvesting:
- Converts body movements (walking, stretching) into electricity.
- Generates power from wind, water waves or vibrations.
- Medical & Health Applications:
- Wearable health sensors (e.g., tracking finger movement in rehabilitation).
- Pacemakers or medical implants without needing batteries.
- Smart Devices & Robotics:
- Self-powered touchscreens (phones, tablets, ATMs).
