Abstract

We report transparent stretchable single-walled carbon nanotube-polymer composite films that emit pronounced Raman and near-infrared fluorescence with a fine spatial resolution. The independent modulation in Raman and fluorescence spectra is demonstrated in response to touch and temperature. The optical signal transduction of transparent stretchable optoelectronic films may enable a paradigm shift in touch-sensing devices eliminating electrical interconnects.
