The health monitor that requires no skin contact

A small band with sensors designed by a city-based startup can track basic health parameters, without direct contact with one’s skin.

The device was developed with the support of the National Institute of Mental Health and Neuro Sciences (Nimhans).

From the heart rate of an individual to sleep pattern, functioning of the vital organs of the human body can be tracked with the health monitor, ‘Dozee’, developed by a group of entrepreneurs. The small strip-like band, about the width of the shoulder, is placed under the mattress when one sleeps and is left plugged. Data is gathered while the user is asleep.

Multiple vibro-acoustic sensors on the band follows the user’s movement on the mattress, gathering all the basic data. The band is linked to a mobile phone application, which receives processed data on the heart rate, respiration, stress levels and sleep.

“If there is an unusual change in the heartbeat, immediate alerts are sent to the phone. This could be life-saving. It is beneficial for someone who wishes to monitor a loved one living at a far off place as well,” said Mudit Dandawate, founder, Turtle Shell Technologies.

Pritish Gupta, head, marketing, said that even during its initial days after the launch, Dozee saved many lives. “In one of the patients, the breathing pattern was unusual. On examining, we found water accumulation in the lungs. Similarly, a case of tuberculosis was also identified.”

As an effective replacement for polysomnography (a diagnostic used in sleep medicine), Dozee can help assess sleep disorders, particularly Obstructive Sleep Apnea. This is a condition where a person stops breathing altogether in sleep.

“Each session of having a sleep disorder tested could cost anywhere between Rs 8,000 to Rs 10,000 in private clinics. One might be able to purchase the equipment at the same price and use it regularly,” said Dr Bindu Kutty, HOD, Neurophysiology, Nimhans. She said the device was tested at their facility.

The entrepreneurs are working with the experts at the Jayadeva Institute of Cardio Vascular Sciences and Research to document the use of the device in a clinical setup.

How to use Dozee

The device, which is a small strip about the same thickness as a jute rug, can be placed below the mattress that the user sleeps on. Data is gathered by sensors. Dozee is designed to collect data from one individual at a time.
