It is now an everyday news [17] that the wearable
electronics devices and technologies, such as heart rate
monitors, smart watches, tracking devices (including PillCam)
and smart glasses (google glass), etc. are experiencing a period
of rapid growth. Fitness devices are by far the most mature
market, making up 97% of the projected value in 2013, though
this will fall dramatically as smart watch and smart glasses
categories develop and products with embedded sensors
that track and analyse physical or other movements and
activity. Future wearable technology reports that the wearable
technologies will impact future medical technology, affectingour health and fitness decisions, redefining the doctor-patient
relationship and reducing healthcare cost. Looking at the
bigger picture, Futuresource research [17] points out that the
wearable electronics technologies will undoubtedly continue
to expand in consumer sectors, and also acceptance will
continue in other sectors, in particular healthcare sectors, and
the market growth at a value of over $20 billion by 2017.
