HCM CITY (VNS) — Wireless sensor networks are an effective solution to take care of patients and support physicians in the treatment process, researchers told a three-day international conference that opened in HCM City yesterday.
Researchers at Thai Nguyen University, Thai Nguyen University of Information and Communication Technology, and Ha Noi University of Science and Technology presented a wireless sensor to monitor the heartbeat and body temperature, including for outpatients.
It consists of two sensor nodes attached to the patient and a base node to collect data from them. The data received is displayed on a computer screen, allowing doctors to monitor a patient's health status from a distance.
The system is simple and efficient, allowing patients to wear the device on their body without affecting normal activities.
With the convergence of microelectronic technology, integrated circuit technology, sensor technology, and signal processing, etc, scientists can increase the applicability of wireless sensor networks at low cost.
In Viet Nam, where overcrowding in hospitals has for long been a concern, the new sensors will help address this problem.
But there is little research or development done in the field in Viet Nam.
Similar devices have to be imported from abroad at high cost while demand is very high.
The new system would help reduce cost for hospitals, the researchers said. — VNS
