ActLight's Dynamic PhotoDetector (DPD) technology presents an advanced method of photodetection, tailored specifically for wearable devices. Unlike traditional photodiodes, which rely on a static mode to detect light, the DPD engages a dynamic approach. By measuring the delay time of a significant forward current induced by pulsed voltage, this method ensures exceptional sensitivity down to single-photon detection without the need for amplification. This innovation results in faster and more precise sensor readings that are critical for effective wearable applications.
The DPD technology is not only remarkable for its sensitivity but also for its energy efficiency. Operating at low voltages, it eliminates the need for high-voltage systems typical of standard photodiodes. This reduction in power requirements allows wearable devices to extend their battery life significantly, making them more practical and appealing for everyday users. Additionally, the compact size of the DPD sensor aligns perfectly with the miniaturization trend in wearable technology.
Furthermore, the versatility of ActLight's DPD allows it to be seamlessly integrated into a variety of wearable devices, including smartwatches, fitness trackers, and health monitors. The enhanced sensitivity and low power draw make it ideal for real-time biometric measurements, such as heart rate and activity levels, providing users with accurate and actionable health insights.
