16、rdization 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 Inte
17、rnational 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 participat
18、e 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
19、 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
20、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 m
21、isinterpretation 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 na
22、tional 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 service
23、s 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 Nation
24、al 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
25、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
26、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 n
27、ormally 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
28、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. 4 IEC TR 62899-250:2016 IEC 2016 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all part
29、s 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 rel
30、ated 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. IMPORTANT The colour inside logo on the cover page of this publication indicates that it c
31、ontains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. IEC TR 62899-250:2016 IEC 2016 5 INTRODUCTION Recently, along with a variety of other expanding electronic technology applications, one
32、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 p
33、articular 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 in
34、terest 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 u
35、sing 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 fo
36、r future standardization work in wearable electronics. 6 IEC TR 62899-250:2016 IEC 2016 PRINTED ELECTRONICS Part 250: Material technologies required in printed electronics for wearable smart devices 1 Scope This part of IEC 62899, which is a Technical Report (TR), explores a new technological field
37、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 No terms and
38、definitions are listed in this document. ISO and IEC maintain terminological databases for use in standardization at the following addresses: IEC Electropedia: available at http:/www.electropedia.org/ ISO Online browsing platform: available at http:/www.iso.org/obp 4 What are WSDs? Wearable smart de
39、vices 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
40、 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
41、has come up with new processes to produce those new devices. 5 WSDs 5.1 General Figure 1 shows an overview of WSDs, including categorization and examples. This graphic introduces categories based upon characteristics, such as prior art, stretchable, ultra-thin and biocompatibility, and some examples
42、 in each category. Technologies and challenges for those examples are discussed in Subclauses 5.2 to 5.5.

43、od fit for the shapes of the human body. The major functions of these devices are to acquire vital data and/or movement of the body, and to transfer data to other devices and/or networks without human interaction, unlike cell phones or portable music players, which require human interaction. For exa
44、mple, the following WSDs are already commercialized: bracelets, watches and wristbands; eyewear and headmounted devices; earphones; finger rings, necklaces and the like. In order to realize these devices, adaptation of the following characteristics is required: a small footprint, lightness, lower po
45、wer, mechanical flexibilities to follow body movement, and if needed, display functions with higher resolution and/or mechanical flexibilities. Obviously and most importantly, in addition to fulfilling these electrical or mechanical needs, additional safety requirements and regulations need to be de
46、veloped, since WSDs will operate in close contact with the human body. 5.3 Textile integrated type Textile integrated type WSDs combine integrated biomedical signal acquisition functions with communication functions attached to clothing such as sportswear or underwear. This type of WSD needs complem
47、entary technologies compatible with the electronic components and textile products that make up the clothes. Specifically, highly flexible and stretchable wiring technologies are required. Furthermore, electronic components need to withstand stresses similar to those general clothing is subjected to
48、, such as stresses which occur during washing and drying.
