The Dynamic PhotoDetector (DPD) tailored for hearables introduces an advanced level of precision in bio-signal monitoring, which is highly beneficial in achieving real-time metrics such as blood oxygen levels and heart rate. Traditional photodetectors require constant reverse bias and significant amplification to measure light intensity, a process that often introduces noise. However, ActLight's DPD innovatively shifts this process to measure delay time with a forward bias, enhancing signal quality without extra amplification.
This technology offers tremendously high sensitivity, capable of detecting minute changes in light intensity. This ability allows it to function effectively in a range of light conditions—ideal for hearable devices that operate in varied environments. Whether used in fitness monitoring or in day-to-day wellness assessments, DPD in hearables offers reliable biometric data, making it a critical component for next-gen health-focused technology.
ActLight's technology boasts low power consumption due to its operation solely on Vdd, eliminating the need for high voltage inputs and ensuring streamlined energy usage. Incorporating standard CMOS processes, it allows for straightforward integration into manufacturing procedures, reducing both costs and complexities while maintaining top-tier performance.
