The objective of CARDIS is to investigate and demonstrate the concept of a mobile, low-cost device based on a silicon photonics integrated laser vibrometer and validate the concept for the screening of arterial stiffness, detection of stenosis and heart failure.

For meeting this objective the consortium will:

– Investigate, design and fabricate optical subsystems and components:

  • A  Photonic Integrated Chip with a multi-branch laser interferometer with integrated photo detectors and input port for an external micro-optical laser assembly
  • A micro-optical laser assembly
  • A micro-optical lens system

– Integrate the subsystems and build a multi-beam interferometric laser vibrometer
– Develop a process flow scalable to high volumes for all sub-systems and their integration steps;
– Investigate and develop the biomechanical model to translate optical signals related to skin-level vibrations into underlying CVD physiological events;
– Validate the system in a clinical setting
