The Atlantic paid a visit to Google’s medical sciences lab to speak with Google X Project Manager Andrew Conrad to discuss the team’s work on a wristband that utilizes nanoparticles to detect the early presence of cancer cells in the wearer’s blood. As part of the early testing process, Google has developed a sort of synthetic skin.
When they were casting and making these arms, they had to make them out of materials that behave like human skin. They have to have the same autofluorescence and biochemical components of real arms.
