Overview

IEC TR 63071:2016 – "Power supplying scheme for wearable systems and equipment" is a Technical Report from the IEC that provides models and frameworks for power-supplying schemes for wearable devices. It focuses on interoperability, interfaces and measurement methods for wearable power systems (including energy-harvesting) rather than on specific power-generating technologies. The report is intended as state-of-the-art guidance for designers, integrators and test organizations working on wearable power supply and on‑body charging concepts.

Key Topics

• System models and terminology - Defines concepts such as energy harvest and kinetic generator and describes existing models (e.g., wristwatch with secondary battery, solar cell + battery, kinetic generator).
• Physical and logical interfaces - Addresses physical connections (wired connectors, cables, wireless links) and logical connections (protocols for power control and information exchange).
• Charging scenarios - Distinguishes charging while worn versus charging when removed; discusses on-body power generation and supply when the power source and device are on different body locations.
• Energy-harvesting sources - Notes common harvest sources (movement, pressure, thermal gradient, perspiration, light) and device types (solar cells, Peltier elements, kinetic devices, MEMS) while explicitly not specifying their design details.
• Measurement methods and interoperability - Emphasizes the need for standardized measurement approaches and interoperability testing for wearable power-supplying devices.
• Use cases and examples - Includes practical examples such as generators in shoes, animal tracking and wearable sensor systems.

Applications

IEC TR 63071 is practical for:

• Wearable device manufacturers designing power architecture for watches, earphones, headsets, smart textiles, shoes and medical sensors.
• System integrators planning wired (e.g., USB Type-C) or wireless power delivery between a generator and client wearable.
• Test laboratories and certification bodies developing measurement methods and interoperability tests for wearable power-supply systems.
• Standards developers and regulators assessing health, safety and efficiency considerations for on‑body charging and wireless power transfer.

Practical benefits include clearer models for on‑body energy harvesting, guidance on connector/protocol choices, and a framework to evaluate charging scenarios and interoperability for wearable power supplies.

Related Standards

• IEC 62680 series (USB interfaces, including USB Type‑C) - referenced as an example for wired connectors and logical interfaces.
• IEC Electropedia and IEC TC 100 publications - for related terminology and multimedia system context.

Keywords: wearable power supply, energy harvesting, kinetic generator, on-body charging, USB Type-C, wearable systems, power-supplying scheme.

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 63071, which is a Technical Report, has been prepared by 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
