【Abstract】 A new method for actuating micro parts is introduced. A PZT plate is attached to the MEMS chip, generating mechanical movement. The momentum is transferred from silicon die to the micro part. Two kinds of base principle, actuating by pulse and actuating by vibration, were discussed in detail. The important results made by foreign researchers were introduced. The viewpoints and advices for further research were proposed.更多还原
