Fingerprints are signal processors for touch, enhancing the way we sense the world. Now robots have access to the same trick
In recent years, biomechanical engineers have discovered that fingerprints don't just improve grip, they also perform a delicate type of signal processing. The ridges modify vibrations in the skin in a way that best allows human nerve endings to receive them and this allows the skin to extract much more information from touch than it otherwise would. We discussed this idea almost two years ago.
