Ultra small, very low power heart rate sensor for hearables? You need the ActLight Dynamic Photodiode!
Lausanne 25.11.2019: Long battery life, precision of measurements and very small size are the key requirements for vital signs monitoring sensors in hearable devices.
Despite ultra small detector area (<0.2 mm2) and minimal LED power (<1 uW/Hz), the sensor delivers convincing >70 dB SNR. In addition, the ActLight solution provides a very strong output signal without AFE, further reducing the power consumption of the overall system.
The Dynamic PhotoDiode is the vital signs monitoring sensor of choice to meet the very demanding technical requirements of the hearable devices market.
