This paper describes the design, fabrication and characterization of parylene-based C-shape actuators. The actuators flatten out in response to temperature changes created by ohmic heating of built-in thin film resistors. The devices are fabricated by micromachining processes using parylene C and four metal layers. Mathematical modeling of operation temperature, displacement and load capacity was carried out and verified experimentally. The device operates on less than 0.33 V input voltage and 90 mA input current. During operation, the temperature of the actuator is less than 32 °C. This actuator has an 11 µN load capacity, 5 mm of tip displacement and a bandwidth of 1.4 Hz.
