摘要
This chapter is devoted to the design of electro-thermal micro-actuators with capacitive position feedback. Analytical and finite element solutions of the electro-thermal and thermo-elastic problems are presented. A separate section is devoted to the challenging problem of displacement determination using charge sensitive amplifiers for high-precision capacitance measurements. These are illustrated with examples of electronic measurement circuits tested by the authors.
