With this, it is possible to non-invasively examine, in real-time, the oral cavity of patient for presence of precancerous or cancerous lesion in less than 15 minutes as compared to 48 hours required by the conventional biopsy procedure. Researcher from department Nitin Kumar said it took 10 years to make the device.

Drip for smart hospitals

Pradeep Kumar and Rohit Chaudhary, students from SISTec, have displayed an intravenous drip monitoring system using Arduino for smart hospitals. Under current medical care system, the monitoring of patients in a hospital throughout the day is a tiresome process. Sometimes, doctors or nurses are too busy, so they can't monitor each patient. “In order to reduce workload and overcome critical situations, we proposed a system called Automated Intravenous Drip Monitoring System,” Pradeep said.
