8Gartner

Hype Cycle for Wearable Tech

“Providers of wearables are generally not meeting expectations set in the media and are no longer buoyed by hype.”

9Gartner

Hype Cycle for Wearable TechSuccessful depends on:

integration with parallel ecosystems for (health, entertainment content, IoT solutions, connected home or finance)encourage long-term use via incentives, new content, online groups, or organizationsuse data analysis, while respecting user privacy.

10Gartner

Hype Cycle for Wearable Tech“The return on investment from actual business cases is still being proven….

Most devices on the Hype Cycle for wearable devices have a moderate benefit rating.”

11

Textile Electronic Wearables Today“Jess, to be honest…no one in this industry is making any money because there is not yet a market need.”- Innovation Director at large E-textile manufacturer*

*Verified by multiple times by CEO & CTOs

Takeaways: For the moment, we are in a busy space.

Our industry has a use-case problem that needs to be solved (quickly) before parallel technology threats outpace smart garment maturation.

Our industry needs to be predictive on use-cases so we can guide regional and global R&D…it will also help with the $$$.

U.S. Standards System vs. Other Countries

An Introduction: American National Standards Institute & United States Standards System, NC State StandardsWorkshop, Tony Zertuche

U.S. Standards Systemreliable – flexible – responsive

Market driven

Flexible and sector-based

Industry-led and government-supported

This system is designed to . . .Support a broad range of stakeholder engagementAddress emerging priorities and new technologiesAllow stakeholders to find the solutions that best fit their respective needs

As defined in the United States Standards Strategywww.us-standards-strategy.org

Standards Trade Barriers

Overly prescriptive or unique standards

Duplicative or burdensome testing or inspection procedures

Difficulty in knowing how to comply with

mandatoryrequirements

Labeling requirements that are not meaningful

or are misleading

Concerns about release of proprietary

information during testing

Product bans (not justified by science;

may be discriminatory)

Watch type wearable device can;

track the older person’s location in everywhere,assist for navigation, instruction and communication in everywhere, watch health condition not only for older persons but also for all in everywhere.

Wearable Product Platforms

35

Trends:Detachable puck for ‘heart’ of electronics & battery necessary for washing.

High gauge wires for interconnecting devices to ‘heart’ of electronics – moving to conductive inks.

Conductive fabrics used of biopotentialsensors. Some move to conductive inks and silicones.

Complicated processing results in high cost and low product throughput. Call for automation, but investment price is not yet justified.

High shelf cost for maintaining inventory.

Evolution of Materials

36

Conductive yarns: good availability; textile-like; complacent in materials innovation (no market need); challenging retrofit application

Conductive Pasteshigh materials & process innovation (flexible electronic markets); polyurethane & PVA growth; Retro-fit application

Conductive Inks (ink-jet)Improved materials/performance cost vs. screen print; back to fiber-level integration; multi-layer device design capable

Vapor Phase ProcessingBroad materials scope; patterning techniques well established in flex circuitry and semiconductor industry.
