Editor's Notes
This is one module of the MCS, which consists of linear, rotation comb actuators and micro containers. Micro containers are moved by comb actuators through ratchet mechanisms and rollers. They can move straight or rotation. Each MCS system has dimension of 1cm2. This system can be used in bio-chemical analysis for classification of small samples, assembling machines or micro total analysis system ( -TAS).
