Development of Miniature Temperature Sensors
Abstract
Phase I work demonstrated temperature sensors formed from polyacrylonitrile and similar polymers which could be applied from solution onto a substrate, then subsequently ion implanted to have conductivity in the kiloohm to megaohm/square range. If desired, the films could be patterned before implantation to small geometries by lithographic procedures. The resulting films had a large, negative temperature coefficient of resistance, and the resistance-temperature response was reproducible and retraceable within experimental error over multiple cycles. The films were extremely durable and solvent-resistant. A quasi-one dimensional hopping mechanism for conduction was indicated from the conductivity versus temperature and conductivity versus pressure measurements.
