Abstract

See full text

A small hemispherical drive apparatus actuates the cilia to undergo the limit cycle oscillations. Electromagnets are positioned on a housing of the apparatus. A gimbal with shaft is also attached to the housing. The shaft has a first end within the housing that is proximally separated and remains separated from the electromagnets as the shaft rotates. Generated signals excite electromagnets in sequence to produce an electromagnetic track for the shaft.
