Environment-safe transistor developed in India

Researchers at Shiv Nadar university in Delhi-NCR have developed a new high performance, organic field-effect transistor (OEFT). They claim the transistor to be a revolution in the field of agriculture, with a touch of sustainability. India is a largely agricultural nation, and this biocompatible technology can be a great asset to the farming industry.


The transistor is enabled to detect the level of toxicity in soil, with respect to the number of herbicides, insecticides and fertilizers etc. It can also test the levels of heavy metal contamination in the groundwater and detect these plants for any diseases. This will be achieved with the help of sensors, which perform high-quality analysis but are quite more cost-effective than the conventional ones.

According to the developers, affordability is achieved by the organic nature of semiconductors. By using bio-soluble salts, they are made much more eco-friendly and feasible.

Associate Professor at Shiv Nadar University, Smarendra Pratap Singh said that organic electronics are the need of the hour and the key to a sustainable future.

The team of researchers includes Yogesh Yadav, a PhD student and Sajal Kumar Ghosh, Associate Professor at Shiv Nadar University. They discovered the inexpensive materials and processing steps of these OEFT devices will serve as preferred equipment for the desired applications.
