Question

Describe what is the physical principle of thermo-mechanical micro-actuators? a difference in the youngs modulus of the two materials specific shapes of the two materials a difference in the electrical conductivity of the two materials a difference in the thermal expansion coefficient of the two materials unanswered

Answer 1

Explanation:

where α is the material's coefficient of thermal expansion. A simplified illustration of thermal ... than the other and the actuator bends to accommodate the different deflections.
