Towards an implantable telemetry system for S p O 2 and PWV measurement in small animals

We report preliminary work on an implantable telemetry device for photo-plethysmography based vital signs monitoring with a recently reported multi-sensor and parallel processing system-on-chip. The envisioned system would enable monitoring of arterial oxygenation, heart rate, blood pressure and respiration rate with a single optical probe implanted on an artery — a less invasive method than the current state-of-the-art.
