MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541134179 A) filed by Rajalakshmi Engineering College, Chennai, Tamil Nadu, on Dec. 31, 2025, for 'a pilot scale process for manufacturing flower-like neodymium-doped sno2 for alcohol sensing applications.'
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 vital for improving road safety and minimizing the risk of 5 accidents. Among these systems, portable alcohol sensors are particularly important, as they determine a driver's Blood Alcohol Concentration (BAC) through breath analysis. The present application employs an innovative and economical metal oxide perovskite material synthesized via a chemical route and thoroughly characterized for its alcohol sensing performance. Using this material, a trace-level alcohol detection device is developed to 10 enable accurate measurement of alcohol in exhaled . breath. This approach represents a significant advancement in the development of low-cost, high-performance sensing materials for medical and safety-related applications. The core innovation is the use of perovskite materials as the primary sensing element, which provides distinct advantages over conventional alcohol detection technologies. 15 The study further describes a pilot-scale process for producing flower-like neodymium-doped Sn02 perovskite tailored for alcohol sensing applications. The process focuses on precise control of material composition and processing conditions to achieve high consistency and reproducibility. This reliable synthesis route facilitates the production of neodymium-doped Sn02 and the fabrication of a highly sensitive alcohol vapor sensing device, thereby 20 contributing to a notable advancement in accurate. and dependable alcohol detection technology."
