Question: What is the most ground breaking thing u made

My current research, we are developing a clinical device to measure oxygen-gas concentrations inside the lungs of preterm babies just using light!

On the way to develop this technique, I created realistic thorax phantoms, which are silicone dolls with exactly the same geometry of the main organs of the baby (lungs, heart, bones, muscle, trachea, fat and skin). The silicone was mixed with silica micro spheres and dyes to mimic the optical properties of human tissue. In other words, when you shine near infra-red laser on this dolls, light will behave in a very similar way it would do with real babies.
I also created 3D computational models of the thorax of the baby to simulate how light travels inside us.
