The smartwatch market alone has become more competitive — nearly doubling in size to $13 billion in three years, according to market research firm Euromonitor.Samsung Electronics debuted the Galaxy Watch Active 3 this year. The device includes a blood oxygen monitor, as well as features for sleep and blood pressure.Samsung sees those medical functions as a “key strength” for its wearable devices. With the “data collected we can create a lot of great services and products for consumers to help them live healthier lives,” Yang said.The company will continue to set up partnerships with other healthcare firms to make products, Yang said.This year, Samsung partnered with AIA Korea on the life insurer’s healthcare app — called AIA Vitality. The app encourages people to lead healthy lifestyles by offering insurance discounts.
