Abstract
A device such as a sensor for use in an atomic force microscope. The device comprises a first oscillator, a second oscillator, a pair of first co-axial members interconnecting the first and second oscillators for torsionally suspending the first oscillator, a support structure, and a pair of second co-axial members whose axis is orthogonal to an axis of the first co-axial members and which interconnect the second oscillator and the support structure for torsionally suspending the second oscillator.
