This asymmetric U-shaped thermal actuator consists of a narrow “hot” arm and a wider “cold” arm connected in series to an electrical circuit. When current flows through the actuator, Joule heating produces more heat in the narrow arm and results in greater thermal expansion compared to the wide arm.
The transient response FEM simulation was performed using Elmer 9.
The results shown in this video were obtained with ParaView 6.
