Pulse Oximeter

For Fitness and Medical Applications

Renesas MCUs integrate the on-chip A/D and D/A converters required in pulse oximeters, as well as an LCD drive-control circuit. These on-chip features reduce the number of external components making the MCUs ideal choices for compact size and low cost pulse oximeter solutions.

This pulse oximeter solution provides a single platform for digital health, provides easy industrial and mechanical design, and enables seamless integration for fitness and medical applications. These applications include fitness trackers, smartphone cases with integrated bio-sensing, athletic garments, worker safety, and mobile or tabletop pulse oximeter devices. Power and timing devices are available to complete the solution.

Key Features:

  • Measures heart rate, blood oxygen concentration, respiration rate, heart rate variability (stress), ambient light level, proximity, and color RGB for circadian rhythm
  • Fully integrated, ultra-thin form factor
  • Factory calibrated pulse oximeter; no end of line calibration required
  • Invisible optical sensing; works behind IR ink and simplifies industrial design
