Abstract
A humidity-sensing material based on C-60 is described whose conductiv ity is mediated by the amount of water vapor to which it is exposed. I ts response is quick enough to follow the breathing of a person from a distance of 30 cm. The characterization of the material by DC polariz ation, AC admittance, and near-IR photoacoustic response measurements as well as UV-vis spectra is reported and the preparation of both bulk and thin-film specimens described. Work to resolve the composition an d the sensing mechanism of the material in more detail is in progress.
