The Biomatrix is an machine in Ben 10: The Alien Generation
The Biomatrix first shed light in the episode Arduous and was a prototype omnitrix. It turned out that it contained two AI: ADAM (Artificially Designed Anatomical Male), and EVE (Extensive Virginal Ellegancy) that would randomise themselves into the male and female of the species they scanned. They take upon Azmuth's idea to create a device that could secure the life of any species, but it lacked the self-awareness of the Unitrix. Beside that, it still used the concept of having a separate device for each species. Azmuth ended up putting it in storage.
