Wireless Body Area Network for Preventing Self-Inoculation Transmission of Respiratory Viral Diseases

This paper proposes an idea ofWireless Body Area Networks (WBANs) based on Bluetooth
Low-Energy (BLE) standards to recognize and alarm a gesture of touching the face, and in effect, to
prevent self-inoculation of respiratory viral diseases, such as COVID-19 or influenza A, B, or C. The
proposed network comprises wireless modules placed in bracelets and a necklace. It relies on the
received signal strength indicator (RSSI) measurements between the bracelet and necklace modules.
The measured signal is cleared of noise using the exponential moving average (EMA). Next, we use a
classification algorithm based on a Least-Squares Support Vector Machine (LSSVM) in order to detect
facial touches. When the results of the classification indicate that the hand is moving toward the face,
an alarm is sent through the neck module and the vibrator embedded in the wrist module is switched
on. Based on the performed tests, it can be concluded that the proposed solution is characterized
by high accuracy and reliability. It should be useful,
