Earbud-Embedded Micro-Power mm-Sized Optical Sensor for Accurate Heart Beat Monitoring

Download Whitepaper
This work demonstrates that accurate hear beat monitoring, via photoplethysmography (PPG), can be performed at micro-power consumption level with an ear worn device. This is achieved thanks to the combination of a highly sensitive low power PPG chip, an optimal optical module, and an ergonomic design of the wearable device.
