Theoretical analysis reveals key performance factors in electrothermal actuators for MEMS applications, suggesting enhanced security mechanisms.

The analysis shows that electrothermal energy conversion in actuators enhances security functionalities in MEMS systems.
Using finite element analysis, critical parameters for actuator deformation and displacement were quantitatively assessed, demonstrating effective control.
The mathematical model, established with a lumped parameter design, helped predict actuator behavior under multi physics coupling conditions.
Results indicate that specific V-beam parameters significantly influence the deformation of the electrothermal micro-actuator, optimizing performance.

Liu et al. (2025) studied this question.
