The BioTac sensor has a soft, flexible skin over a liquid filling
The BioTac sensor's fingerprints enhance the sensor’s sensitivity to vibration
The BioTac sensor can correctly identify a randomly selected material from a a sample of 117 common materials 95 percent of the time
The BioTac sensor has potential in prostheses and robotics applications
We’ve seen the development of a number of technologies that could be used to provide robots with a sense of touch, such as proximity and temperature sensing hexagonal plates and artificial skin constructed from semiconductor nanowires. However, perhaps none are as impressive as a tactile sensor developed by researchers at the University of California’s Viterbi School of Engineering. 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.
