Just when you thought fingerprint sensors was cutting-edge technology, Gelsight comes along, a new 3D surface sensing material that can detail at even microscopic levels.
Gelsight has many applications such as using it as a 3D scanning sensor and even find out the small details in a bullet mark. This is pretty top-notch stuff, I wouldn’t be surprised to see it implemented in future 3D fingerprinting applications. See Gelsight.com for more details.
