20、 International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and
21、 electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical com
22、mittees; any IEC National Committee interested 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 f
23、or 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 committe
24、e 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 ac
25、curate, 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 regi
26、onal 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
27、 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 agen
28、ts 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,
29、or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some o
30、f the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62779-1 has been prepared by IEC technical committee 47:Semiconductor devices. The text of this standard is based on
31、 the following documents: FDIS Report on voting 47/2267/FDIS 47/2277/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

The committee has decided that the contents of this publication will remain
33、 unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page
34、 of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. BS EN 62779-1:2016IEC 62779-1:2016 IEC 2016 5 INTRODUCTION The IEC 62779 series is composed of t
35、hree parts as follow: IEC 62779-1 defines general requirements of a semiconductor interface for human body communication. It includes general and functional specifications of the interface. IEC 62779-2 defines a measurement method on electrical performances of an electrode that constructs a semicond
36、uctor interface for human body communication. IEC 62779-31defines functional type of a semiconductor interface for human body communication, and operational conditions of the interface. IEC 60748-4 gives requirements on interface integrated circuits for semiconductor devices. Especially, Chapter III
37、, Section 7 in this standard is applied to interface circuits for a communication network using a general channel, such as wire or wireless. However, a channel for HBC is the human body whose channel properties, such as signal loss and delay profile, are different from the general channel, so Chapte
38、r III, Section 7 cant be applied to an interface for HBC. Furthermore, a standard on a communication protocol for body area network (BAN) IEEE 802.15.6, which includes a communication protocol for HBC was published in 2012. A common interface for HBC should be defined to secure communication compati
39、bility between various devices that are implemented on/inside the human body or embedded in peripheral equipments. _ 1To be published.

40、art of IEC 62779 defines general requirements for a semiconductor interface used in human body communication (HBC). It includes general and functional specifications of the interface, as well as limiting values and its operating conditions. NOTE Additional information on HBC is provided in Annex A.
41、2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
