The skin even has fingerprints that enhance the sensor’s sensitivity to vibration, so that as the sensor slides over a textured surface, it vibrates in characteristic ways. The group’s BioTac sensor was built to mimic a human fingertip and can outperform humans in identifying a wide range of materials, offering potential use for the technology in robotics and prostheses.
