A MEMS-based pneumatic micro-conveyor for planar micromanipulation
Résumé
This paper present a two dimensional pneumatic actuator based on silicon MEMS technology for objects micro-manipulation using tilted air jets. The device is composed of three layers stacked together, two micro-machined silicon wafers and a Pyrex glass wafer. The system is composed of a set of micro-conveyors in about 9 mm x 9 mm area. Each micro-conveyor has four nozzles and can generate tilted air-jets which allow four conveyance directions. An experiment of the conveyance of a silicon chip of 3 mmdiameter and weighing approximately 2 mg was performed with pulsed air flow.
