Wearable devices have emerged as the next big market opportunity in the electronics industry. Smart watches are among the most popular wearable items today. The healthcare market, including the medical, fitness and wellness sectors, promises even broader opportunities. The majority of wearable gadgets have a number of things in common.
Wearable devices must:
– Be always ready for use
– Be small and lightweight in order to be easy to wear
– Last a sufficiently long time on a re-charge or on a disposable battery
– Support short periods of activity, spending the majority of time in idle or sleep mode
– Last a very long time in idle or sleep mode
