Wearable biosensors for monitoring patients

Sir, One of the problems in patient care is lack of continuous monitoring of vital signs in those who need health care and long‐term treatment. Wearable biosensors are an example of new technologies in the health care area and provide opportunities for continuous monitoring of vital signs in patients, athletes, premature infants, children, mental patients, people who need long‐term care, elderly, and those who live in remote areas and do not have access to health care services. A textile‐based wearable system for vital sign monitoring in cardiac patients has been suggested. This vest is made of a conductive fabric which can measure heartbeat and breathing rate during activity or at rest and send information to a processing center. This way, people’s health can be monitored after discharge from the hospital.[1] Patients’ referral to healthcare centers leads to waste of time and money for them and the health system. Remote monitoring using smart biosensors can decrease patients’ referral to health centers up to 30% [Figure 1].[2]
