Monolithic bridge-on-diaphragm microstructures   Abstract Monolithic bridge-on-diaphragm (BOD) microstructures for sensor applications were fabricated by means of laser machining and anisotropic etching techniques. The pressure-frequency-characteristic was measured by acoustical excitation of the microbridge to resonant vibrations and optical detection of the resonance frequency. In the pressure range between 0.8 bar and +1.0 bar the pressure-frequency-characteristic is…
