Corduroy Entering Metaverse With Robotic Sensors
Scientists have developed a robotic sensing system that can distinguish different fabric types, including corduroy, and potentially bring a detailed sense of touch to virtual reality. The system uses a flexible slip sensor that mimics human fingerprint features to recognize small features on surface textures when touched or sliding across the surface.
The flexible slip sensor can gather data by sliding across the surface of the material under investigation and can identify a range of 20 fabrics at 100% accuracy at a steady speed and 98.9% accuracy at random sliding rates.
The research team, led by Chuan Fei Guo from Southern University of Science and Technology, claims that previous attempts to create “touching” sensors at a human sense level were inadequate due to reliance on physical stimuli.
The sensor was built from tunable electric double layers with a nanoscale electric charge separation, achieving sensitivity up to 51,900 Pascals pressure and spatial resolution down to 15 micrometers spacing and 6 micrometers in height. The artificial sensory system can respond to both static pressure and high-frequency vibrations during physical interaction with textures or other objects.
