Patent for Health-Monitoring Biometric Attendance System
New system measures heart rate, blood pressure, and temperature during biometric attendance, building a seven-day baseline and sending confidential weekly reports to HR. A patent was granted in 2026.

The Indian Patent Office has granted a patent to a team at Chandigarh University for an attendance system that monitors three vital signs during the daily biometric scan. The device measures blood pressure, heart rate, and body temperature at the same moment a person clocks in or out.
Dr Vikas Wasson, a professor in the computer science department and director of engineering foundations at the university, said the invention targets a blind spot in workplace and campus health management. "Almost every day, millions of us walk up to a biometric machine," he said. "Rather than only recording who showed up, the enhanced biometric sensor also reads three vital signs."
The system does not flag a single elevated reading. Dr Sachin Kalsi, an associate professor in mechanical engineering and head of academic operations, said a stressful morning commute can spike anyone's heart rate or blood pressure. The device monitors each individual over a seven-day period to build a personal baseline. Only a sustained deviation from that baseline triggers an alert.
Readings are never shown on the screen. "A person confronted with alarming numbers may panic and worsen their own condition," Dr Kalsi said. Instead, the weekly data flows confidentially to the human resources or administrative team, which can then take action – arranging a medical check-up, a lighter workload, or a conversation.
The three sensors exist today as separate instruments. Dr Wasson called the integration the real novelty: "fusing quiet health monitoring into routine biometric attendance, so that emotional and physical distress can be detected early, within the natural rhythm of everyday life, without asking anyone to do a single extra thing."
The research team also included three Chandigarh University students – Rishabh Raj, Paras Gupta, and Vikas Sharma.
