Abstract

A bilayer actuator made of carbon nanotubes (CNTs) and boron nitride (BN) is developed that can withstand high temperatures. The bilayer actuator can be powered quickly to a temperature up to 2000 K within 100 ms and can operate at frequencies from sub-Hertz to about 30 Hz due to the low heat capacity of the thin CNT layer.

Keywords: bilayer design; high sensitivity; high temperature; solution processes; thin-film actuators.
