ASUS is announcing the VivoWatch 6 today, a new flagship smartwatch that the company says is the world's first to be able to detect blood pressure and electrocardiogram via fingertip, featuring not only two sets of medical-grade ECG and PPG sensors, but also a bioelectrical impedance (BIA) sensor on its outer ring that enables users to measure their body composition. The watch, which weighs only 60 grams, is also advertised with dual-band GPS and up to 14 days of battery life.
