Phase transitions that produce small length changes (even on the order of nanometers) due to thermal expansion or magnetostriction can be resolved by making contact between the tip of a miniature piezo-resistive cantilever and a sample.
The cantilever is incorporated into a bridge circuit allowing for the measurement of subtle changes in the deflection of the cantilever. The small footprint of the cantilever makes this measurement compatible with small sample spaces where rotation is possible.
