ams OSRAM's tiny chip LEDs are set to bring greater reliability and accuracy to compact wearable devices. Accordingly, heart rate monitoring technology is expected to become more precise and battery efficiency is expected to improve, expanding the functions and scope of use of wearable devices.

ams OSRAM has recently launched a new ultra-small chip LED featuring a 500μm chip that enables even more precise signal quality.

This product measures 1.2 mm × 1.0 mm × 0.6 mm, slightly larger than a grain of sand, but provides a high optical output of 14 mW, significantly improving the accuracy of biosignal monitoring.

ams OSRAM's chip LEDs deliver 20% more brightness than conventional models, enabling more efficient photoplethysmography (PPG).

PPG technology measures changes in blood flow in blood vessels by shining green light on the skin and analyzing the reflected signal, which can greatly improve accuracy, especially in wearable devices such as smart rings and in-ear devices worn on fingers or earlobes where blood flow is abundant.

Additionally, it can extend the life of battery-powered devices while realizing lower energy consumption than before, contributing to increasing the efficiency and sustainability of wearable devices.

“ams OSRAM has a long history in vital sign monitoring and is further accelerating the development of ultra-compact, high-performance products,” said Florian Lex, Product Marketing Manager at ams OSRAM. “The new chip LEDs ensure reliable heart rate monitoring even in small, tightly designed devices.”
