According to the latest 2018 infrared sensing application report from LEDinside, a division of TrendForce, pulse oximeter heart rate sensors in digital health have been completely introduced into smartwatch and wristband markets. They have been gradually introduced into other wearable devices, applied in sports training, home care and automotive driver monitoring markets. Because there are around 400 million patients, suffering from diabetes in the world, blood glucose monitoring market has high potential. Most blood glucose monitors are invasive.
