Real-time detector for hypervelocity microparticles using piezoelectric material

Degradation of Space Exposed Surfaces by Hypervelocity Dust Dombardment - Example: Solar Cell Samples

“…3 shows some typical particle morphologies of extraterrestrial particles. Modern new detection systems for hypervelocity microparticles using piezoelectric material have rather recently been developed (Miyachi et al, 2004). Furthermore, a dust cloud of Ganymede has also been detected by in situ measurements with the dust detector onboard the Galileo spacecraft (Krüger et al, 2000).…”

Effect of Heating and Cooling on the Piezoelectric Properties of a PZT Sensor for Mercury Dust Monitor

“…Another promising physical property for the in-situ observation is momentum of each dust particle. Through electrostatic accelerator experiments, a good correlation has been found between particle momentum and the amplitude of the oscillational collision signal 5,6) . Our plan is to establish an empirical equation for the estimation of particle momentum from a signal form through calibration with electrostatic accelerators and a light gas gun.…”

Multimodal characteristics of a piezoelectric lead zirconate titanate element impacted with iron particles having velocities above 20 km/s

“…Published by Elsevier Ltd. All rights reserved. doi:10.1016/j.asr.2011.04.007 heavy ions (Miyachi et al, 2006;Takechi et al, 2008a), it is sufficient for detecting hypervelocity microparticles (Miyachi et al, 2004). In addition, because of the piezoelectricity of the PZT element, the element can function as an active detector.…”
