MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541134181 A) filed by Rajalakshmi Engineering College, Chennai, Tamil Nadu, on Dec. 31, 2025, for 'pilot scale process for producing flower-like praseodymium doped sno2 with enhanced alcohol sensing capabilities.'
Inventor(s) include Dr. N. T. Mary Rosana; and Dr. K. L. Vincent Joseph.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "Alcohol detection systems are essential tools for enhancing road safety and reducing accident 5 risks. Among these, portable alcohol sensors play a pivotal role by measuring a driver's Blood Alcohol Concentration (BAC) through breath analysis. This application leverages an innovative, cost-effective metal oxide perovskite material synthesized using a chemical method and rigorously characterized for its alcohol sensing capabilities. A trace-level detection device will be developed using this material, enabling accurate detection of alcohol 10 in exhaled air. This novel approach represents a breakthrough in designing affordable, highperfomlance sensing materials for medical and safety devices. The key innovation lies in utilizing perovskite materials as the primary sensing component, offering significant advantages over conventional detection methods. This study outlines a pilot-scale production process for flower-like Pr-doped-SnOz 15 perovskite, specifically optimized for alcohol sensing applications. The method emphasizes precise control of material proportions and processing parameters to ensure consistency and reproducibility. This robust process enables the reliable production of Pr-doped-SnOz and the fabrication of a highly sensitive alcohol vapor sensing device; marking a significant" advancement in precision alcohol detection technology."
