36 FOREWORD
37 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
38 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
39 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
40 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
41 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
42 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
43 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
44 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
45 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
46 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
47 consensus of opinion on the relevant subjects since each technical committee has representation from all
48 interested IEC National Committees.
49 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
50 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
51 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
52 misinterpretation by any end user.
53 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
54 transparently to the maximum extent possible in their national and regional publications. Any divergence between
55 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
56 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
57 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
58 services carried out by independent certification bodies.
59 6) All users should ensure that they have the latest edition of this publication.
60 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
61 members of its technical committees and IEC National Committees for any personal injury, property damage or
62 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
63 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
64 Publications.
65 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
66 indispensable for the correct application of this publication.
67 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
68 rights. IEC shall not be held responsible for identifying any or all such patent rights.
69 IEC 63203-401-1 has been prepared by IEC technical committee 124: Wearable electronic
70 devices and technologies. It is an International Standard.
71 The text of this International Standard is based on the following documents:

91 Introduction
92 Generally, strain sensors (strain gauges) utilize changes in the electrical resistance of a thin
93 copper-nickel alloy coating formed on a polymer film such as PET film. The strain sensor is
94 bonded to the object to be measured, and the strain in the strain sensor caused by the strain in
95 the object to be measured is detected as a change in resistance of the thin metal film.
96 As is obvious from the sensor’s material and structure, the object to be measured is mainly a
97 high elastic modulus member such as a metal material, the amount of strain detected is very
98 small, and the resistance change that is the output is also small. Therefore, it is common to
99 detect resistance changes as voltage changes using a Wheatstone bridge circuit, without
100 directly measuring resistance values. In the range where the relationship between strain change
101 and resistance value change is linear, the proportionality constant between the two is called
102 the gauge factor. Several existing standards are known for gauge factor measurement and are
103 listed in Bibliography.
104 On the other hand, the strain sensor covered by this standard utilizes the change in resistance
105 caused by the deformation of a conductive material in which conductive filler is dispersed in a
106 stretchable polymer material (such as an elastomer).
107 However, compared to the strain sensor using thin metal film described above, the target strain
108 range and resistance value change range are significantly different, so new testing methods for
109 this type of strain sensor are needed. ED1 of this standard was published with unresolved
110 technical issues such as the confusion between evaluation of sensor devices and evaluation of
111 sensor materials.
112 In ED2, the test method has been fundamentally reviewed and revised as a measurement
113 method for sensor devices.
