The Key difference between a wearable electronics and smart phones is, wearable device is in extreme proximity to the user. Devices such as smart watch is always feeling the skin of the user and also physical movements/activities.
With such a physical closeness to the user of the devices, wearable device is a better option for health and activity monitoring rather than smart phone. So more number of sensors can go into wearable compared to smart phone. With this trend of wearable device preference for health and activity monitoring, IHS estimates the shipments of sensors used in wearable electronic devices to grow by 7x times from 67 million in 2013 to 466 million in 2019.
In future, more number of sensors are expected to be integrated inside wearable devices. Due to this, the growth in shipment of sensors is expected to be higher than the shipment of wearable device itself.
To give you an idea of shipment forecast for wearable devices, IHS has forecasted wearable device shipment to increase to 135 million units in 2019 from 50 million in 2013.
MEMS is the most popular sensor device even now and in the future also. accelerometer, gyroscope, pressure sensors and also microphone are going to be mems-based. Any device which need to be monitoring motion directly and indirectly can be mems-based.
To monitor the health there are different set of devices, which includes photonic heart rate monitors, and photonic Oximeters ( to measure oxygen in the blood), body temperature sensors ( Can be thermistor based or infrared based), and also ambient weather condition monitors such as humidity sensors, pressure sensors.
IHS predicting a very big growth in shipment of sensors in wearables after the beginning of shipment of Apple smart watch, which is going to be sometime in next year. So by 2015, IHS forecasts a jump in shipment of wearable sensors by 600%.
IHS finds STMicroelectronics leading the sensor market, with growth in share. In 2013, ST has garnered a share of 26% compared to 20% in 2012 in wearable sensor market, as per IHS. It can be easily estimated ST continues to grow its share in 2014.
STMicroelectronics offers lot of reference designs by combining its mems devices along with its STM32 32-bit microcontroller product line. The ready reference designs helps innovative engineers to quickly develop a product for any application where the sensor is available.
To give you some information on wearable semiconductor market, information network has recently forecasted the wearable semiconductor market to reach US$ 9 Billion by 2019 with compound annual growth rate of 30% from 2015 to 2019.
