Attendees: Johnson, Massion, Klimov, O'Reilly

KJ: Want to keep cost cheap, less than $5K; want low power, suitable for profiling float deployment

No moving parts
Micro-electrode array exposed to external flow
Could have programmable electrode spacing to vary sensitivity
Probably don't need concurrent CTD
Shape of electric field is complex

TO: Would standard calibration beads with known size distribution help?
How about adaptively driving which electrodes are paired as particle moves across surface?

Hope for 5-200 um range - size spectrum
Impedance spectroscopy
