Dynamometer

Micromachined Dynamometer

This micromachined dynamometer is used to determine the coefficient of friction by measuring the normal and tangential forces.

Dynamometer Beam

The beam shown exerts a normal force on the smooth "gear" of the microengine.

Flex Link Close-up

The standard microengine flex link is shown here, and is used to rotate the smooth "gear."

Pin Joint Close-up

This is a close-up look at the pin joint on the smooth "gear."

Dynamometer Verniers

Verniers for measuring deflection used to calculate the tangential force.

Vernier Close-up

Close-up of parallel vernier structure.

Dynamometer Verniers

Vernier Close-up

Close-up view of one vernier; the teeth are 2 microns wide and the spaces between them measure 4 microns.

Contrast of Textures

In this image the texture differences between vertical and horizontal surfaces are visible.
