English abstract:
This study reports on a novel bi-stable actuator with an integrated aluminum nitride (AlN)
piezoelectric layer sandwiched between two electrodes. To achieve bistability, the membranes must
exceed a characteristic compressive stress value, also called the critical stress. For this purpose, we
used highly c-axis orientated stress-controlled AlN with a thickness of 400 nm. First experiments
showed, that it is possible to switch between the two stable ground states with at least two
rectangular pulses at a frequency of 80 kHz and with a voltage Vpp of 40 V, resulting in a
displacement of about 10 μm for each switching direction.
