Multiphysics FEM-simulation

Hardware & Software

  • with ANSYS(R) FEM-program for
  • UNIX (DEC-Ultrix, HP-UX) workstations
  • and PC-486 (MS-DOS) personal computers

MEMS Micro-sensors

  • MEMS-sensors based on silicon resonators with piezoelectric thin-film layers (AlN, ZnO)
  • and etched quartz crystals (DETF: Double-Ended Tuning Fork)
  • bimorph structures (silicon & PZT ceramic)

FEM - Finite Element Method

Silicon

  • piezoelectric simulation of MEMS sensors & actuators
  • silicon resonators & actuators (beams, diaphragms, cantilever, etc.)
  • with ZnO & AlN piezoelectric thin-film layers for excitation & detection
  • hybrid bimorph Si bimorph-structures with PZT ceramics (PoC)
  • triple-beam force sensors based on silicon / ZnO thin films

Quartz

  • HF-etched quartz crystals with Au electrodes
  • use of different quartz cuts
  • Double-Ended-Tuning-Fork (DETF)

PZT ceramics

lead zirconium titanate, commonly abbreviated as PZT:

  • PZT (Pb[Zr(x)Ti(1-x)]O3), one of the world’s most widely used piezoelectric ceramic materials
  • here: Siemens VIBRIT420 (Data sheet 1981), SIEMENS Piezokeramik PZT
  • Datenblatt VIBRIT®, Piezoelectric Ceramics from Siemens, Redwitz
  • VIBRIT - Piezoceramics from Siemens, Ord.-No.: N-281/5035-101
