Test fixtures for testing layers of touch screen material and methods for using the same. Some test fixtures include first and second test beds that are movable relative to each other, an impedance measurement circuit, an electrical connector, a clamping actuator, and a processor, where the test fixtures and/or test fixture components are configured to secure a layer of touch screen material and measure the electrical impedance of at least one feature of the layer. Some of the present methods include securing a layer of touch screen material between test beds, calculating an electrical impedance of at least one feature of the layer, and releasing the layer from the test beds.
