Pulse Oximeter

Measuring and recording blood oxygen saturation through non‑invasive, real-time monitoring is crucial across clinical, home, and emergency settings. This pulse oximeter platform enables next-generation connected healthcare and is available in both a compact wireless fingertip design and a handheld design. Powered by Bluetooth^® Low Energy (LE) SoCs or an all-in-one Wi‑Fi^® and Bluetooth LE module, both platforms support ultra‑low power processing, integrated USB charging, and seamless wireless connectivity. The system provides accurate SpO₂ measurements. Paired with an advanced analog front end (AFE), optical front end, and sensors, accuracy is achieved by accounting for ambient influences such as motion, skin temperature, and variations in skin pigmentation.

The design also delivers a clean power supply for the AFE's analog and receiver sections, improving LED safety and efficiency while maximizing battery life. Together, these capabilities enable a compact, high‑performance oximeter ideal for premium consumer wellness and remote monitoring applications.

System Benefits:

• The fingertip system can integrate crowdsourced location (CSL) tracking compatible with Google's Find My Device and Apple's Find My^® network to help prevent loss or misplacement.
• The handheld system supports a larger display for advanced bio-signal metrics and includes a dedicated capacitive touch controller to enable advanced HMI capabilities.
  • Sensing on the handheld platform is separated from processing and display, providing sensor design flexibility across fingertip, wristband, or patch form factors.
• Compact, low‑power, rechargeable system design reduces size, cost, and complexity.
• AI‑ready architecture supports advanced signal-processing algorithms that are robust against common pulse oximetry error sources.
