Second, micro-vibrations are registered by a pressure sensor mounted on the inside of the sensor’s core, enabling the measurement of surface roughness and texture. This is where the fingerprints add a lot of value, as they interact with textures.
By placing all electronics inside a rigid core and covering them with a compliant replaceable bladder, this sensor is able to function more robustly while providing sensitive human-like measurements. Electronics such as this could someday be a normal sight on robotic hands, offering a real human touch that allows a robot to identify material and grip it appropriately.
