A Light Touch

CBC News was one of the outlets reporting on a new sensor under development at the University of Nebraska in Lincoln. The technology uses light, as well as semiconductive material particles, to image objects and enable an astoundingly delicate sense of touch—to distinguish, for instance, among letters on a coin. The report is drawn from a paper published in the journal Science.
