In-situ instrumentation for the measurement of cosmic dust is an excellent tool in Dust Astronomy. The Cosmic- Dust-Analyszer onboard Cassini provided unique information about interplanetary dust and about the dust distribution in the Saturnian system. The simultaneous determination of the grain properties like speed, charge, mass and composition is possible by current methods. Typical impact ionisation sensors are sensible to dust grains with sizes between 0.01 and 50 micron and with impact speeds between 1 and 300 km/s. Recent instrument developments allow for further improvements of dust grain trajectory and compositional measurements. The current sensor technologies are compared with new concepts and their applications. Future missions to the moon or to the inner solar system require more accurate and highly reliable detection techniques.
