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.
More recently, interest in using AFM to measure nano-scale forces has prompted researchers to deal with AFM cantilever spring constant calibration issues.
Each laboratory was asked to perform cantilever spring constant calibration procedures on the test cantilevers using procedures with which they were familiar.
Given the much greater ease of use, this technique would seem a very desirable tool in a cantilever spring constant calibration method arsenal.
Precise atomic force microscope cantilever spring constant calibration using a reference cantilever array.
The reference cantilever method is used to calibrate AFM cantilever spring constants.
Calculation of the test cantilever spring constant is performed according to the steps suggested in ref.
Technically this is a cantilever spring, loaded with a mass: the classic mass-spring system.
The section using this cantilever spring finishes with a practical application: the ruler-putty combination uses the same principle as the tines in a music box (available for a few dollars).
The MMA system features dual active cantilever spring
contacts that deliver low insertion/withdrawal forces without jeopardizing normal forces needed for a reliable connection.
