Here’s the latest advance in tactile sensors. From the SciAm article:
The device, a so-called electroluminescent thin film, glows in response to applied pressure. The result is a finely detailed image of the texture of any object that touches the film. [...] Because the sensor produces data in the form of an optical image, the data can be quickly and easily collected by simply photographing the image. This represents a major step forward in the ease and efficiency of collecting information from tactile sensors. Quick data collection is critical to performing real-time tasks, for example grasping a tool with a robotic arm. If the tool starts to slip, the image produced by the electroluminescent film immediately shows the tool’s motion, and the robot’s grip can then be adjusted to prevent it from falling.
Of course, this technology could be applied to either robots or cyborgs, although the latter would involve translating the image received into immpulses the human brain would understand.
