3D-printed skin is a manufactured outer layer designed to give a device extra functions, such as touch sensing, impact protection, grip, or environmental monitoring. In robotics, it can act like a tactile sensor array: pressure, vibration, or contact changes are turned into signals that the controller can use.
In cyber security, this matters because the skin is no longer just casing; it becomes part of the trusted input path. If the layer is damaged, poorly calibrated, or tampered with, a robot may misread touch and make unsafe or incorrect decisions. Attackers could exploit that by physically interfering with the surface, while defenders can reduce risk through calibration checks, material inspection, redundancy, and sensor validation. Treating tactile materials as security-relevant components helps protect both function and safety.
