Abstract
ABA type block copolymers as a new class of temperature sensing polymers with tunable, high temperature coefficient of resistance (TCR). A sensor includes a heater, a thermal insulator between two thermometer layers, the heater generating a thermal gradient within the thermal insulator. The thermometers give an indirect measurement of fluid flow around the sensor, based on their temperature readings. The thermometers are flexible layers including ABA block polymers.
