Accelerating Innovation In Biometrics And Medical Devices Through The Modeling Of Human Tissues
Application Notes
Optical system simulation is essential for the development of medical applications, Photoplethysmography (PPG) sensing using smartwatches, facial recognition, and fingerprint authentication. In this context, the accuracy of biological tissue models significantly impacts the development process. Human skin consists of multiple tissue layers—including the epidermis, dermis, and subcutaneous tissue—each possessing distinct optical and physical properties. This layered structure affects the propagation, absorption, and scattering of light within the tissue; if the modeling is inaccurate, discrepancies may arise between simulation results and actual conditions.
Therefore, accurately reproducing the skin’s tissue structure serves as a critical foundation for the design and analysis of reliable optical systems. However, modeling biological tissue remains a very challenging task.
