Study on the movement of the eye with applications in electromechanical microdrives

This paper presents general aspects of the eye, along with a multitude of experiments performed in order to obtain the most suitable micro-drive. There are described theoretical aspects about the movement of the eye, as well as the results of each experiment and conclusions. Final models are also included in this paper. Research thesis - Given the types of eye movements and the range of values of this bio-drive, the purpose of this research theme involves: research, theoretical studies and technical experiments regarding new unconventional systems of electromechanical drive, based on micro motors and micro actuators with different operating principles: piezo, electrostrictive, electro thermal, electromagnetic, electrochemical as well as other operating principles that can have a great contribution to the drive of a spherical object, in different directions and with different mechanical parameters. Great emphasis will be put on the control of the direction, speed, acceleration, as these unconventional systems can also be applied in robotics, medicine, and bioengineering. Domains of value of the micro drive: ● specific geometry and the structure of the micro muscular system ● angular displacement areas ● linear displacement areas ● micro forces of the drive ● mechanical micro couples ● micro forces ● micro couples of the micro biomechanical resistance Characteristics and mechanical parameters: ● Spherical diameters: 0-200 mm ● Linear areas: 0-5 mm ● Angular areas: 0-60 ● Meridian plans ● Micro forces areas: 0-100 cN ● Micro biomechanical couples areas: 0-100 cNcm ● Power: 0-100 W ● Temperature areas: 0 – 60 ● Speed area: 0-30 rpm
