Hello, everyone!
Today, I would like to share with you the medical application scenarios on WBAN (Wireless Body Area Network) technology.
Sensor nodes attached to or implanted into a human body may be used in the use of Wireless Body Area Networks (WBAN) in medical environments. These sensor nodes can sense biological information from the human body and communicate it across a short distance to a control device worn on the body or located in an easily accessible location.
Medical signals such as electrocardiogram (ECG), photoplethysmogram (PPG), electroencephalography (EEG), pulse rate, blood flow, pressure, and temperature should be detected by a sensor node electronics that is miniaturized and low-power.
Fig. 1. The system is a wireless body area network. The gateway CCU collects and monitors data from individual wireless sensor nodes on a single human body.
The acquired data from the control devices is subsequently sent to remote locations via a wireless body area network for diagnostic and therapeutic purposes, which also includes a long-range wireless network (See Above Figure 1).
The great majority of monitoring systems have previously been designed and are in use in medical systems. Currently existing solutions rely on wired connections, and their electronics are heavy, especially when a large number of sensors are connected to a wireless device.
Each and every wire connection in a monitoring system is inconvenient and unsuitable for patients to wear since it restricts their mobility. As a result, WBAN necessitates the use of individual wireless sensor nodes with no cable connections.
Individual sensor nodes will send physiological data directly to a control unit (CCU), which will subsequently send it to remote stations for diagnostic and health-care reasons.
I will continue to share on this article in the following post.
