The core of a WBAN is its sensor network, which includes both wearable and implantable devices designed to operate with minimal power consumption and high data fidelity. Wearable sensors can be integrated into clothing, wristbands, patches, or glasses, while implantable sensors are surgically placed for more accurate and continuous internal monitoring. These devices are configured to collect and wirelessly transmit physiological signals to a coordinator node, which often serves as a processing and communication hub. The system is engineered for low-latency communication, minimal electromagnetic interference, and energy efficiency. Communication protocols commonly used in WBANs include Bluetooth Low Energy (BLE), Zigbee, UWB (Ultra-Wideband), and IEEE 802.15.6, which is specifically designed for low-power and short-range medical data transmission. The network must ensure secure and reliable transmission of sensitive health data, maintaining robustness against body movements, environmental noise, and potential cyber threats.
The most significant benefit of WBANs lies in Remote Patient Monitoring (RPM). With the ability to continuously track critical health indicators, WBANs can detect anomalies and send alerts to healthcare providers or caregivers in real-time. This early detection is vital for managing chronic conditions like diabetes, cardiovascular diseases, or neurodegenerative disorders. For instance, a diabetic patient can wear a Continuous Glucose Monitoring System (CGM) integrated with WBAN, which tracks glucose levels and alerts both the patient and physician if values cross predefined thresholds. Similarly, patients with cardiac arrhythmia can be monitored with wearable ECG sensors, providing early detection of irregular heartbeats and preventing potential emergencies. RPM also facilitates post-operative care and rehabilitation, enabling physicians to monitor recovery remotely and intervene only when necessary, thereby reducing hospital readmissions and optimizing resource allocation [2].
However, the implementation of WBANs is not without technical and ethical challenges. One of the major hurdles is energy efficiency battery life of sensor nodes must be long enough to avoid frequent replacements or surgeries in the case of implants. Energy harvesting technologies such as thermoelectric, piezoelectric, or RF energy are being explored to overcome this limitation. Additionally, WBANs must ensure data privacy and security, as they deal with sensitive health information. Secure communication protocols, encryption techniques, and user authentication are essential to protect against cyberattacks and unauthorized access. From an ethical standpoint, issues like informed consent, user autonomy, and data ownership must be addressed. Furthermore, the physical design of sensors must prioritize comfort, biocompatibility, and unobtrusiveness to encourage long-term use by patients, particularly elderly or cognitively impaired individuals.
