The sample is scanned by a pyramidal tip, which is set on a flexible cantilever spring fixed to an x-y-z piezo.
The spring constant using this method can be evaluated based on the reference cantilever spring constant and the gradient of the force curve obtained during the measurement.
If the nontorsional spring constant [K.sub.zz,p] of the anchors of the micropaddle was in a comparable range as the AFM cantilever spring constant, then the slope would also be a function of distance based on the relative values of [K.sub.p], [K.sub.zz,p] and the membrane compliance.
Several other methods are placing a tipback cantilever spring made of 17x 25 TMA wire, de-impacting spring, push coil spring from first to second molar, bonded attachment to second molar, crossed tipback springs made of 17x 25 inch TMA wire.
The challenge is that what is actually being measured is the cantilever deflection in volts by the PSD, which requires calibration of the cantilever spring constant or stiffness [N/m] and the optical lever sensitivity on the photodetector [V] to ultimately convert to force.
In free space, [f.sub.0] is dominated by the AFM cantilever spring constant and cantilever's effective mass.
More recently, interest in using AFM to measure nano-scale forces has prompted researchers to deal with AFM cantilever spring constant calibration issues.
(Technically this is a cantilever spring, loaded with a mass: the classic mass-spring system.)
The MMA system features dual active cantilever spring contacts that deliver low insertion/withdrawal forces without jeopardizing normal forces needed for a reliable connection.

Cantilever spring constants and Q-factors were computed using a data processing program that was written in MATLAB (MathWorks, Natick, MA).
The usual method, involves soldering the brushes onto standard cantilever springs. This spring design, however, results in force levels diminishing over time, often ending in premature motor failure.
