A biometric sensor for wearables – LG Innotek
LG Innotek has released an ultra-thin optical biometric sensor module designed to be used in wearables and smartphones to measure health parameters such as heartbeat, stress indicators and blood oxygen saturation level. The new sensor is more accurate than it’s predecessors achieving ±5 bpm range of error and consumes very little power to operate. At stable heartbeat rate an accuracy of ±2 bpm can be achieved, which is as good as conventional medical instruments. The module is just 1 mm thick and contains a photodiode, five LEDs and an IC.
