Abstract:
1. A method of detecting resonance in an element comprising: locating a counter electrode a predetermined distance from an element such that the element and the counter electrode are in a non-contact mode, wherein the element comprises a semi-conductive material or a carbon nanotube and has a length of less than about 500 μm and a width of less than about 50 μm; inducing an electrostatic force on the element by applying a first electric signal to the counter electrode; generating a second electric signal at the semi-conductive material or the carbon nanotube in direct response to the induced electrostatic force; directly examining the second electric signal and; ascertaining the presence of at least one subharmonic or superharmonic of the resonant frequency of the element in the second electric signal.
