Abstract
The invention relates to a micromanipulator (1, 8, 14, 35) which is used to produce a relative movement between said micromanipulator and an object (7, 13, 25, 34). The micromanipulator (1, 8, 14, 35) has piezoelectric movement elements (3, 10, 15, 16, 17, 43, 44, 45) which are provided with end pieces (6, 12, 22, 23, 24, 46, 47, 48). The inventive micromanipulator is characterized in that the end pieces (6, 12, 22, 23, 24, 46, 47, 48) are magnetic or can be magnetized.
