Semiconductor devices - Semiconductor interface for human body communication - Part 2: Characterization of interfacing performances (IEC 62779-2:2016)

This part of IEC 62779 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. This part includes general and functional
specifications of the measurement method.
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 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. Quality of a
data transmission strongly depends on a coupling degree between the grounds; hence, it is
important to maintain the coupling degree between grounds of a signal transmitter and
receiver for an accurate measurement of the electrode’s performances. This part defines a
measurement method to measure electrical performances of an electrode while the coupling
degree between grounds of a signal transmitter and receiver is maintained.
NOTE 1 HBC semiconductor interface consists of an electrode and analog front end.
NOTE 2 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 a data transmission and a
HBC application.

L'IEC 62779-2:2016 définit une méthode de mesure des performances électriques d'une électrode qui constitue une interface à semiconducteurs pour les communications via le corps humain. Dans la méthode de mesure, un émetteur de signaux est isolé électriquement d'un récepteur de signaux. Ceci assure le maintien de l'isolation entre l'émetteur et le récepteur pour mesurer avec exactitude les performances d'une électrode. La présente partie inclut des spécifications générales et fonctionnelles de la méthode de mesure.

Polprevodniški elementi - Polprevodniški vmesnik za komuniciranje človeškega telesa - 2. del: Opredelitev značilnosti vmesniških zmogljivosti (IEC 62779-2:2016)

Ta del standarda IEC 62779 določa merilno metodo za električno zmogljivost elektrode, ki zajema polprevodniški vmesnik za komuniciranje človeškega telesa (HBC). Pri merilni metodi je oddajnik signala električno izoliran od sprejemnika signala, s čimer se ohranja izolirano stanje med oddajnikom in sprejemnikom, ki omogoča natančno meritev zmogljivosti elektrode. Ta del vključuje splošne in funkcionalne specifikacije merilne metode. Pri komuniciranju človeškega telesa se uporabnikovo telo uporablja kot medij prenosa na podlagi povezave prek bližnjega polja: oddajnik in sprejemnik signala sta povezana prek bližnjega polja, ki se ustvari v človeškem telesu in zraku. Bližnje polje je močno zlasti znotraj telesa (zaradi dielektrične konstante v telesu), kar omogoča prenos podatkovnega signala po telesu z modulacijo bližnjega polja. Oddajnik in sprejemnik signala za komuniciranje človeškega telesa vključujeta notranji ozemljitvi, ki sta pri večini načinov komuniciranja človeškega telesa
ločeni druga od druge, medtem ko se ohranja stanje povezave po zraku. Kakovost prenosa podatkov je zelo odvisna od stopnje povezave med ozemljitvama. Zaradi tega je pomembno, da se stopnja povezave med ozemljitvama oddajnika in sprejemnika signala ohranja za natančno meritev zmogljivosti elektrode. Ta del določa merilno metodo za merjenje električne zmogljivosti elektrode pri ohranjanju stopnje povezave med ozemljitvama oddajnika in sprejemnika signala.
OPOMBA 1: polprevodniški vmesnik za komuniciranje človeškega telesa vključuje elektrodo in analogni čelni del.
OPOMBA 2: splošne tehnike analogne in digitalne modulacije je mogoče uporabiti za modulacijo bližnjega polja pri komuniciranju človeškega telesa, ustrezna tehnika modulacije pa se določi v skladu z zahtevanimi zmogljivostmi za prenos podatkov in način komuniciranja človeškega telesa.

in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.

Part 2: Characterization of interfacing performances



1 Scope
This part of IEC 62779 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. This part includes general and functional
specifications of the measurement method.
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 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 throug
