SMART FABRICS

1. Introduction

Smart Fabrics, also known as intelligent textiles, electronic textiles or e-textiles, have attracted

considerable attention worldwide due to their potential to bring revolutionary impact on human life. These

are the fabrics with the ability to react to different physical, mechanical, electrical, thermal and chemical

stimuli. Smart Textiles are also defined as Smart fabrics and Interactive Textiles (SFIT).

Smart Clothing, wearable technology, wearable computing and intelligent clothing projects involve the use

of e-textiles. Smart fabrics are distinct from wearable computing because emphasis is placed on the

seamless integration of textiles with electronic elements like microcontrollers, sensors, and actuators.

Smart Fabrics need not be wearable. For instance, they are also found in interior design.

Smart Fabrics can be broadly categorized into two categories namely embedded and integrated. The

classical electronic devices such as conductors, integrated circuits, LEDs, and conventional batteries are

embedded into garments. Also, the passive electronics such as conductors and resistors or active

components like transistors, diodes, and solar cells are integrated into the fabrics.

The scope of smart fabrics industry is potentially enormous in terms of different types of the materials

available, usable technologies and potential applications, and eventual market size. This field includes

phase change, electrically conductive, shape memory, and chromic materials and the enabling

technologies include polymer development, nanotechnology and the embedding of components into

fabrics. The potential sectors to which smart/intelligent fabrics can be applied include commercial, retail

and industrial with applications such as location monitoring devices, entertainment, communications,

actuation & environmental response and sensing & biophysical monitoring.

It is an interesting time for the field of smart fabrics. As the industry matures and develops there is an

increasing drive to turn search results into commercial opportunities.

2. Market Analysis

Smart Fabrics generate a significant body of research with deep implications on everyday life, consumer

market and applications requiring remote sensing, processing and actuation. This has led to a huge

research in this field. According to the Reuters, “The analysts forecast the Global Smart Fabrics in

Interactive Textiles market to grow at a CAGR of 20.91 percent over the period 2012-2016.”1

The current landscape study explores the recent developments in the research of Smart Fabrics. The

focus is to capture the patents published since 2004 in countries such as US, South Korea, Canada,

India, Great Britain China, Australia and so forth.

Three main avenues exist for the Smart Fabrics market:

The advances involving the manufacturing of the smart fabrics.

The type of technology implemented.

The applications of the smart fabrics.

Rather than debating the benefits and drawbacks of this technology, the aim of this study is to establish a

panorama of the intellectual property and the research going on in the field of Smart Fabrics by

systematic study of a relevant patent set extracted by the research team.

3. Global Overview of Smart Fabric Patents

The aim of this section is to study the overall environment of the intellectual property concerning the

development of the Smart Fabrics.

The patent search was conducted using the keywords: textile, smart electronic, fabric, cloth, fiber,

wearable PCB, woven, electric, optic yarn, based on publication date since 2004. The search conducted

for patents from the countries such as US, South Korea, Canada, India, Great Britain China, Australia and

so forth, led to extraction of around 1765 patent applications published since April 2004. Out of these a

total of 520 relevant patent families have been analyzed.

3.1 Priority Trend

The research work in the field of Smart Fabrics started in the year 2001 and grew at a steady pace of

around 3-4 patents per year. The technology accelerated after this era when some of the biggest firms of

the technology world started investing in R&D for Smart Fabrics. The technology became of utmost

importance for the firms when they realized about its deep implications on everyday life, consumer market

and applications requiring remote sensing, processing and actuation. Since then a lot of firms (both small

and large) have started investing in this field and the number of patents filed have gone up enormously.

The number of patent application filings touched a peak in the year 2009 with the maximum patents

having their priority date in this year. However, the fall in 2012-13 does not signify a fall in the number of

patents filed. The fall in the graph is attributed to the fact that only a small percentage of patent

applications filed during the above mentioned period are available in public domain. The rest of the

applications are undergoing processing and are yet to be published by their respective patent offices.

Figure 2: Year wise Patent Priority Trend

Figure 2 shows the patent filing trend (based on priority year) in the field of Smart Fabric Technology.

Research and development had been underway in this field since the start of the 21st century but

accelerated sharply around the year 2009 due to advancements in the electronics domain.

3.2 Priority Country Distribution

An analysis of the location of the priority of patent applications is shown in the figure shown below. The

figures give an overview about all the countries that have initiated R&D related to Smart Fabrics. It can be

observed that USA is the country with most number of priority filings with South Korea at the second

place.

Among the applicants, it is interesting to note that though the maximum amount of work (patents) on

Smart Fabrics has been done in the developed countries like USA and South Korea. In the recent past,

some developing countries like China and Taiwan have also acknowledged the importance of Smart

Fabrics technology and a huge amount of money has been spent on the research in this field.

3.3 IPC Classification

The research team analyzed the resultant patent set and discovered that the following IPC Classes had

maximum occurrences. Their definitions were studied and they also reflected the shifting trend of the

industry from technology integration to specialized manufacturing techniques.

Figure 4: IPC Classifications with maximum occurrences

The figure below shows the number of patent application filings, classified according to the IPC Classes

for a cluster of three years. There has been an overall increase in the number of patent applications filed

as time progresses which is evident from the increasing length of the horizontal bars. The IPC Class

4. Technology Segmentation

4.1 Smart Fabrics’ Classification

Taxonomy was developed by the research team to further analyze the patent set based on the

technology involved, the level of its sophistication and its applications. A change in trend was discovered

during our research that highlighted a shift in the Smart fabrics‟ industry from smartly integrating

technology in existing textiles to manufacturing of smarter fabrics to be converted to textiles. In short, the

earliest advancements in the field simply tried to combine existing electronics with existing textiles to

serve multiple purposes whereas technology at later stages focused more on manufacturing fibers with

inherent electrical properties.

Figure 6: An increasing growth for the fiber manufacturing techniques over technology integration

The shift towards development in manufacturing occurred because clothing and other textile products

must be washable, which subjects the smart elements to water and chemical immersion, physical stress,

and extreme temperatures; the current state of the art tends to be too fragile for this treatment. Hence,

the rate of increase in the number of patent applications for the field of fiber manufacturing was found to

be much higher than the same for the field of technology integration as can be seen in the graph.

The first level classification is based on the same concept. Further classifications narrow down the

specific technologies in both the fields as explained in detail below.

4.2 Manufacturing

Fabric components like the fibers, filaments, films etc. are the beginning stages of a textile. Fabric

components are manufactured into the fabric or textile in several different ways. Fabrics may be woven or

non-woven via adhesive or thermal bonding, tufting, felting, or mechanical interlock. Smart Fabrics and

Interactive Textiles (SFIT) enabling components include electronic components and fabric components

which may provide any or all of the following functionalities: Data processing; Power supply; Input/output

Interfaces; Display; Data communication etc. The conductivity may be added in the fibers at the fiber

manufacturing level, or in the yarn after the fiber is manufactured or as a coating material to be directly

attached on the textile substrate.

Figure 8: Classification based on type of manufacturing techniques

4.2.1 Fiber Development

Multifunctional fibers add useful properties to traditional textile fibers. With various ways to add

conductivity and other properties, fibers may be further classified into the following categories.

4.3 Technology

The scope of Smart Fabrics is very broad to be able to concisely define but the closest attempt may be

saying “traditional fabric with integrated active functionality”. The earliest innovations in the field of smart

fabrics took a rather literal meaning by directly integrating various electronic components with textiles.

Their classification is based on the specific purposes they serve. We have broadly categorized the

technology into three segments: Interface Technologies, Communication and Power Supply Sources.

Their meanings will be further explained in further detail.

4.3.1 Interface Technologies

The interface technologies can be described as the point of communication between the user, his

environment and the electronics of the smart textile. They encompass all the electronic devices and

methods that accept data from the user or the environment and/or provide an output. So, they have been

classified accordingly as Input and Output Interface technologies. The division amongst the two is uniform

as intuitively expected.

Figure 11: Types of Interface Technologies based on direction of information flow in the textile

4.3.1.1 Input Interface

Various input interfaces have been classified as shown below. The first classification is based on whether

the input is coming from the user via textile based buttons and keyboards or whether the input is being

received by textile based body monitoring sensors and electrodes. The „Others‟ category comprises other

interface methods such as audio interface via a microphone etc. The Body Monitoring sensors can be

further sub-divided according to the type of information they sense namely, physiological information, i.e.

the heart rate, pulse rate etc, impact detection information and the body movement/position monitoring

information. The last of the three is performed by few specialized sensors which are classified accordingly

as tilt sensor and pressure sensor.

4.3.1.2 Output Interface

As the name suggests, this classification identifies the types of outputs a smart fabric may provide. It may

be a visual output in the form of an LED, a display or even glowing fabrics. Other types of output may

include tactile or auditory interfaces.

Figure 14: Types of Output Interfaces

As seen from the graph, an overwhelming majority of the patents reveal visual interfaces in the forms

mentioned above. Though with time, there has been an increase in other type of output interfaces as well.

4.3.2 Communication

The research team tried to create further classifications based on the mode of communication, whether

wireless or wired, embedded or woven and some other parameters. However, communication is an

intrinsic aspect of every electronic component in a smart fabric and hence a better classification strategy

was to divide the communication based on the device level namely: Inter device and Intra device.

4.3.3 Power Supply Sources

Any form of electronic component requires power to function. However, conventional power supply

sources are inefficient to be used in a smart textile due to their size and other factors. Button batteries are

one easy option. Other types of sources are being explored in this regard.
