The world’s smallest wearable cardiac monitor

The world’s smallest wearable cardiac monitor, a toffee-sized silicon locket, is almost ready at the Indian Institute of Technology, Bombay (IIT-B).

While the tiny computer that can store a week’s electrocardiogram (ECG) data awaits a manufacturer, it is already in demand. IIT engineers borrow it, rig some adjustments and the locket meant to monitor a heart without hospital visits measures tremors in buildings instead.

“I would be the first to buy one for my mother. The basic device is like plug-and-play,’’ said IIT’s professor Rakesh Lal, of the School of Bioscience and Bioengineering, who conceptualised the project with professor S. Mukherji. “There isn’t another product like the silicon locket,’’ Lal told HT from the University of California where he is a visiting fellow. Similar ECG monitors in the market are walkman-sized or bigger.
