ELECTROSTATIC MICROACTUATORS, ACTIVE THREE-DIMENSIONAL MICROCATHETERS USING SAME AND METHOD FOR MAKING SAME

摘要

The invention concerns an electrostatic microactuator based on SDA ( Scratch Drive Actuators), characterised in that it comprises a large number of associated SDA's and means adapted for applying on the latter an external mechanical prestress providing a superposition of the forces generated by the different SDA's and communicating to an external load the totality of the drive force derived from said SDA's collective performance.
