What is BS EN 62779-2 - Semiconductor interface for human body communication about?
BS EN 62779-2 is an international standard used for semiconductor devices that specifies the general and functional interface of the human body. This interface is useful in determining the electrical performance of the semiconductor interface.
BS EN 62779-2 is the second part of the Semiconductor devices in multi-series that defines a measurement method on electrical performances of an electrode that composes a semiconductor interface for human body communication (HBC). In the measurement method, a signal transmitter is electrically isolated from a signal receiver, so an isolation condition between the transmitter and receiver is maintained to accurately measure the electrode’s performances. BS EN 62779-2 includes general and functional specifications of the measurement method.
Note: HBC semiconductor interface consists of an electrode and analog front end.
Note: General analog and digital modulation techniques can be used to modulate a near field used in HBC, and a modulation technique to be used is determined according to required performances for data transmission and an HBC application.

Why should you use BS EN 62779-2 - Semiconductor interface for human body communication?
HBC uses the body of a user as a transmission medium using near-field coupling inside the body: a signal transmitter and receiver are coupled with each other through a near field that is formed inside the human body and air. The intensity of the near field is strong especially inside the body due to the high dielectric constant of the body, so a data signal is transmitted through the human body by modulating the near field. A signal transmitter and receiver for HBC include an internal ground respectively, and, in most HBC applications, the grounds are separated from each other as maintaining the coupling condition through the air. The quality of a data transmission strongly depends on a coupling degree between the grounds; hence, it is important to maintain the coupling degree between the grounds of a signal transmitter and receiver for accurate measurement of the electrode’s performances.
BS EN 62779-2 defines a measurement method to measure the electrical performances of an electrode while the coupling degree between the grounds of a signal transmitter and receiver is maintained.
BS EN 62779-2 is useful in increasing signal quality for measurement of the electrode’s performances from the human body through an electrode and also helps in processing between the receiving electrode and the analog front end.
BS EN 62779-2 helps you in determining the electrical performance of the semiconductor interface and provides a detailed understanding of the general and functional specification of interface for human body communication.
