1. A flexible substrate testing system, comprising:
a first substrate support structure configured to hold stationary a first portion of a flexible substrate under test;
a second substrate support structure configured to hold a second portion of the flexible substrate;
an actuator configured to move the second substrate support structure to fold the flexible substrate and to unfold the flexible substrate;
a load cell configured to measure a load on the flexible substrate; and
a translation linkage configured to hold the first substrate structure and to limit motion for the first substrate support structure to a direction in which the load cell is configured to measure the load.
