Cusat’s breath sensor spots diabetes risk

Kochi: A team of researchers at Cochin University of Science and Technology (Cusat) developed a tiny, battery-free breath sensor that can detect signs of diabetes from a single exhalation, offering a simple and non-invasive alternative to conventional testing methods.The device, named ‘Miniaturised Triboelectric Breath Acetone Sensor', works by measuring acetone levels in human breath, which are typically elevated in people with diabetes. It can also help identify the risk of ketoacidosis and track calorie burns in athletes. Designed to function without electricity or charging, the sensor generates power from breath. It is made using a nylon film and a copper sheet, making it low-cost and easy to produce. The device delivers quick results at room temperature and eliminates the need for finger-prick blood tests. The research was led by Honey John of department of polymer science and rubber technology and director of Inter University Centre for Nanomaterials and Devices. The team included research scholar Dhanu Treasa Mathew, postdoctoral fellow Anshida Mayeen, and N Manoj of department of applied chemistry and controller of examinations. Researchers said the innovation could play a key role in affordable diabetes screening, particularly in rural areas, while also finding applications for fitness monitoring.
