14、R SUPPLYING SCHEME FOR WEARABLE SYSTEMS AND EQUIPMENT 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-operat
15、ion 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 “
16、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 prepa
17、ration. 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 conse
18、nsus 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 a
19、re 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 t
20、ransparently 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. Independe
21、nt 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 liabi
22、lity 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 (inclu
23、ding 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
24、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 Sta
25、ndards. 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 63071, which is a Technical Report, has been prepared by
26、IEC technical committee 100: Audio, video and multimedia systems and equipment. The text of this technical report is based on the following documents: Enquiry draft Report on voting 100/2751/DTR 100/2816/RVC Full information on the voting for the approval of this technical report can be found in the
27、 report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 IEC TR 63071:2016 IEC 2016 The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website unde
28、r “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document 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 t
29、his 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. IEC TR 63071:2016 IEC 2016 5 INTRODUCTION Wearable devices are being introduced into the market, but
30、each device employs its own power charging method and power source device. Wearable devices are used to support human life and health. The duration and life of the power source, as well as easy charging and replacing of a power source, is a crucial factor for wearable devices that are primarily powe
31、red by batteries. A power generator is one solution for this power duration or life, since it provides power generated by user activities and/or also from environmental sources. Also, connectivity and compatibility of power and data transmission is important. This Technical Report does not specify t
32、he power generating or energy harvesting methods and devices themselves, but focuses on interoperability and measurement methods of power- suppling devices and systems. 6 IEC TR 63071:2016 IEC 2016 POWER SUPPLYING SCHEME FOR WEARABLE SYSTEMS AND EQUIPMENT 1 Scope This document provides models and fr
33、ameworks for the power-supplying scheme for wearable systems and equipment. This document does not specify power generating or energy harvesting methods and the devices themselves. 2 Normative references There are no normative references in this document. 3 Terms and definitions For the purposes of
34、this document, the following terms and definitions apply. 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 3.1 energy harves
35、t technique to obtain energy from surroundings such as electric power from the activity of organisms 3.2 kinetic generator generator that utilizes kinetic energy to generate electric power 4 System model 4.1 General The power-supplying system for audio, video and multimedia systems and equipment can
36、 be applicable to wearable systems and equipment. Among them, the power supplying systems of energy harvesting devices or systems are suitable for the wearable devices because they generate energy. Energy-harvesting devices or systems have already been used in various pieces of equipment such as ele
37、ctronic wrist watches. The existing model is described in 4.2. 4.2 Existing model A major existing model of wearable equipment and power supply is the electronic wristwatch. Power supply methods for electronic wristwatches include: primary batteries, secondary batteries, solar cells with secondary b
38、atteries, IEC TR 63071:2016 IEC 2016 7 a generator with a secondary battery. To charge the secondary battery, wired power transfer is a common method. Its connector is for example a USB connector specified in the IEC 62680 series or other type of dedicated connector. Wireless power transfer is not a
39、 common method for wristwatches, but it is applied for health band type wearable equipment that has also a watch function. However, wireless power transfer is not applied when a wristwatch is worn but applied when it is taken off and when it is charging. Figure 1 shows the example of a solar cell wi
40、th a secondary battery. Figure 1 Solar cell with a secondary battery wristwatch Figure 2 shows the example of a kinetic generator with a secondary battery. The source of this generator is the arm movement. A variation of this type of generator is a stem winding method. It powers a spring that rotate
41、s a rotor. Figure 2 Generator with secondary battery 4.3 System models of wearable devices 4.3.1 Wearable devices Typical wearable devices are: wristwatches, eyeglasses, headsets, IEC Rotating weight Rotor Coil Secondary battery Wristwatch body IEC Light Cover glass Clock face Solar cell Secondary b
42、attery Wristwatch body 8 IEC TR 63071:2016 IEC 2016 earphones, garments and textiles, shoes and gloves. These wearable devices are powered by primary or secondary batteries. If the battery is a secondary battery, it needs to be recharged by electric power. 4.3.2 Charging and connections When chargin
43、g is necessary, it is carried out either while a wearable device is worn or when it is taken off. In case of a legacy wearable wristwatch, major charging shall be carried out when it is removed. In this case, charging is the same as the electronic wristwatch described in 4.2. The potential new appli
44、cation is charging when it is worn. Charging when the wearable device is worn requires the live generation of electric power and a method for supplying the electric power to the clients wearable device. In the case of the wearable device incorporating the generator, the supplying of power and the co
45、ntrol are executed with an internal connection, and no specific standard is needed. When a wearable device and the power-supplying device are located in different parts of the users body, the existing technologies and standards can be considered to provide power and control. In the case where the po
46、wer source and device are connected by wire, existing technologies and USB standards such as USB Type-C 1specified in IEC 62680-1-3 can be suitable. In the case where a wireless connection is desired, industry technologies can be suitable for specific product designs. However, further study would be
47、 needed to determine feasibility of wireless charging standardization for on-body charging applications to study potential interoperability limitations between different physical product designs, locations of the wearable device and the power-supplying device, efficiency, stringent regulatory requir
48、ements for health and safety. The content of this document includes: physical connection: wired connector, cable or wireless connection; logical connection: protocols for power supply and control, and information. 4.3.3 Generator utilizing physical activity of organism There are various types of ene
49、rgy sources from the physical activity of an organism. Movement and other activities of an organism generate electric power called energy harvest. The activities of the body are: natural action or movement, intentional action or movement, pressure, thermal gradient, perspiration, any physiological phenomenon. The energy-harvesting device or system converts these activities into electric power or any other kind of energy. These energy-harvesting devices or
