The Samsung Bio-Processor integrates analog front ends, a digital signal processor, a power management circuit, a microcontroller and eFlash. This means it can do all the necessary processing itself, without external components (other than the sensors). If discrete components are used for the same functionality, they will take up four times as much space
The chip can measure skeletal muscle mass, body fat, heart rate and rhythm, skin temperature and stress level. Combining these individual measurements can enable new use cases for health tracking apps.
Samsung has prepared a wrist band, board and patch reference designs and says that the chip will hit mass production soon. You can expect wearables with the Bio-Processor to be available in the first half of 2016.
