Executive Summary : | The blue economy is expected to contribute to Atmanirbhar Bharat, with India's abundance of water sources leading to the growth of the fish industry. Formalin treatment, which is carcinogenic, is a concern, and human inspection can lead to errors. Resistive sensors, such as two-dimensional nanomaterials like graphene and Mos2, can be a promising alternative due to their small, low-power, and cost-effective nature. The author proposes a fast-operating, low-power, and cost-effective resistive sensor array to determine fish freshness and trace-level formalin. The author also explores gas sensors in agriculture, particularly in the domain of PM2.5 and PM10 concentration. The work involves synthesizing nanomaterials, characterization, fabrication, gas-sensing experiments, sensor array development, and training data using machine learning algorithms. Field trials will be conducted using fish from various marketplaces and local farmlands to assess crop quality and soil quality using the proposed sensor array. |
