A translucent flow-controllable actuator based on the superaligned carbon nanotube films and polymers has been designed and fabricated. The actuator serves as a valve and shows an inspiring concept of controlling the fluid flow without heavy mechanical transmission devices. The flow can be precisely controlled or even shut off by the heating power (or applied voltage), and the process can be clearly observed through the translucent actuator wall. Owing to the advantages of low driving voltage (<6 V), good biocompatibility, great flexibility and long service life (>5000 cycles), the actuator will have great potential applications in the biomimetic field.
