Abstract
Comb-drive actuator operation using the Anderson-bridge is described. The Anderson-bridge is suitable for comb-drive actuator operation because equilibrium of the circuit is obtained by matching of resistances not only for AC but for DC which is required for coupling with mechanical motion and electrical response. We have examined equilibrium of the bridge by measuring bridge output using differential amplifier and tested response of the bridge when external force is applied to the comb-drive actuator.
