Abstract
A sensor including at least one sensor probe including a pair of electrodes; a vertically aligned nanotube disposed between the pair of electrodes; optionally a piezoelectric polymer on the nanotube; and optionally, a field source for generating a field, the field source operatively connected to the pair of electrodes; whereby when the sensor probe is contacted, a change in the field occurs or electricity is generated. Methods of using the sensors are also described.
