<div>Modes of capacitive coupling according to [<a href="/journals/wcmc/2018/9026847/#B73">11</a>]:<i> Ground-Coupling by Touch</i>. The RX device is connected to the external ground, and the TX is a battery-powered device.<i> Ground-Coupling by Proximity</i>. A RX is connected to the external ground, and a battery-powered smart device is close to the RX.<i> Ground-Coupling with a Common Ground</i>. Both devices are directly connected via a common ground and an information flow can be established through the user’s body.</div>
