WILL sticky tape ever cease to amaze? Peeling it can generate terahertz radiation, raising the possibility of a cheaper alternative to lasers for medical imaging.
Peeling sticky tape has already been shown to produce X-rays, so and of the University of Wollongong in New South Wales, Australia, tried to see if it could create lower-frequency terahertz radiation. “We were rather pleasantly surprised to obtain a clear signal in our first attempt,” says Horvat.
Strongly adhesive Scotch Magic 810 tape and weakly adhesive electrical tape both yielded strong terahertz signals, ranging from 0.1 to 10 terahertz, but…
