Optical Sensors have created a growing attention in health
monitoring through various applications that can be integrated with wearable
gadgets which include watches, smart phones and fitness equipment. Optical
sensors enlarge the opportunities through self-observation and also provide features
like pulse rate, oxygen levels and saturation levels through small gadgets for wrist
and fingers which is more convenient.
Wearable optical sensors manufactured with
plastic semiconductors are now currently emerging into the market as low cost
and disposable products. Wearables are significant for regular monitoring and
the main advantage is the product is of light weight, flexible and easy to
manufacture. These are light-based sensors which can be used to monitor the
changes in the body by detecting the muscle contraction and expansion accordingly.
A very stimulating conceivable use of the optical sensor is the process of
monitoring the prosthetic limbs and possibly artificial heart without any
insertion of needles into the body. The optical sensors technology in health
care with various portable devices is driving the medical tests from hospital
to home. The various health monitoring wearable devices that are available in
the market are limited to being fitness devices which would definitely need
sprucing up for use in Healthcare and Medicine.
State of Wearable market in 2015
Most of the applications of wearables are mainly related to health & fitness activity monitoring. Wearable devices get into different applications which are segmented in below diagram.
According to the above figure, majority number
of wearable devices is used in Lifestyle which signifies. The next market for
the wearable optical sensor devices is health and fitness. As per the IndustryARC
analysis, the optical sensors market would reach around $18.7 billion. The
market for optical sensors devices increase as the shipments of tablets and
smart phones increase as the entertainment segment also plays a major role in
the wearables market.
