Poster summary

This paper investigates fat tissue as a medium for communication in IMD systems based on OWC. The findings emphasize the importance of tissue characteristics (temperature in particular) for optimizing OWC performance. This study considered NIR light with 810 nm wavelength and fresh porcine samples to mimic the human tissue. The study employs a realistic measurement approach in an ex vivo setting using various porcine samples: pure fat and flesh tissues and samples with different thicknesses. This study also investigates the influence of porcine temperature on the optical communication channels, which are measured by comparing the received optical power at 23 °C and 37 °C. Tissue samples at warmer temperatures (37 °C) receive higher optical power than colder samples. We also found that porcine with multiple layers of fat (fatty sample) yields higher received optical power than porcine with multiple layers of flesh (muscular).
