Schematics Following are notes from the ITP Flex Sensor Workshop "The impedance buffer in the [Basic Flex Sensor Circuit] (above) is a single sided operational amplifier, used with these sensors because the low bias current of the op amp reduces errer due to source impedance of the flex sensor as voltage divider. Suggested op amps are the LM358 or LM324." "You can also test your flex sensor using the simplest circut, and skip the op amp.
