  We study electrical properties of Taxol-stabilised microtubule (MT) ensembles
in a droplet of water. We demonstrate that the MT droplets act as electrical
switches. Also, a stimulation of a MT droplet with a positive fast impulse
causes oscillation of the droplet's resistance. The findings will pave a way
towards future designs of MT-based sensing and computing devices, including
data storage and featuring liquid state.
