FOREWORD
1) The 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 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 committees; 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 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.
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 of 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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a Technical Report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC TR 62899-250, which is a Technical Report, has been prepared by IEC technical
committee 119: Printed electronics.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
119/104/DTR 119/123/RVC
Full information on the voting for the approval of this technical report can be found in the
report on voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 62899 series, published under the general title Printed electronics,
can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website 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.
A bilingual version of this publication may be issued at a later date.

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.
INTRODUCTION
Recently, along with a variety of other expanding electronic technology applications, one in
particular has gained a lot of attention from different angles. It is referred to as "wearable
electronics". As the name of this new application implies, unlike other electronic technologies,
these are to be attached or applied directly to the human body, such as traditional eyewear.
Due to the particular characteristics of the human body, such as flexibility, this new
technology requires a variety of new and unique capabilities, which other electronics
applications do not need.
In order to realise such applications, electronic technologies are evolving in many areas. One
area of special interest in electronic technology is a new process for producing devices
themselves, called "printed electronics". Unlike conventional production processes called
"subtractive processes", which use subtracting techniques to produce functional devices,
printed electronics (PE) use an additive process using additional techniques by putting
functional materials onto base materials.
Since these electronic technologies are new and rapidly evolving, there are no established
means for their evaluation. This Technical Report intends to resolve this situation from certain
angles and give some guidance for future standardization work in wearable electronics.

1 Scope
This part of IEC 62899, which is a Technical Report (TR), explores a new technological field
to establish standardization activities in TC 119 (Printed electronics) in particular, and to
contribute to the development and market expansion of wearable smart device (WSD)
technology.
2 Normative references
There are no normative references in this document.
3 Terms and definitions

4 What are WSDs?
Wearable smart devices are a newly evolving electronic application field where standards for
conventional electronic devices may not be smoothly applicable. In this new field, electronic
devices are applied or attached directly to the human body like eyewear, contrarily to
conventional electronic devices, such as TV sets, that are most likely to be used away from
the body. Due to the particular characteristics of the human body, these new devices are
required to have new physical characteristics, such as flexibility and salt resistance (anti-
sweat). In order to address those demands, the electronics industry has come up with new
processes to produce those new devices.
