The switchable electric dipole moment of ferroelectric materials could for example be used as a gate for the underlying 2D electron system in an artificial topological insulator.
"The dipoles were placed along the fold lines so that when the origami was compressed, the dipoles bend and become closer together, which causes their resonant frequency to shift higher along the spectrum," says Manos Tentzeris, the Ken Byers professor in Flexible Electronics in the Georgia Tech School of Electrical and Computer Engineering.
