EDS Electrodes
Indium-Tin-Oxide Transparent Electrode Pattern
Spiral-pattern transparent ITO electrodes deposited on protective surfaces (solar cells, optical windows, radiator panels), forming the active element of the electrodynamic dust shield.
Purpose
Spiral-pattern transparent ITO electrodes deposited on protective surfaces (solar cells, optical windows, radiator panels), forming the active element of the electrodynamic dust shield.
Context
Child of L2-DST-EDS within the Lunar Ark system
Principles
- ▸Indium-tin oxide (ITO) electrodes are optically transparent + electrically conductive
- ▸Spiral pattern generates traveling-wave field across surface
- ▸Electrode spacing tuned to particle size (~mm)
- ▸Polyethylene terephthalate (PET) film substrate for flexibility
- ▸Compatible with solar cells and optical windows
Typical implementations
- ▸NASA Kennedy Space Center EDS heritage (since 2004)
- ▸Transparent EDS with ITO electrodes on PET (NTRS 20150016160)
- ▸Firefly Blue Ghost EDS demonstration (2025)
Lunar considerations
- ▸Successfully demonstrated on Blue Ghost Mission 1 (March 2025)
- ▸Long-life PET substrate alternative for high-temperature: polyimide
- ▸Electrode preservation under cumulative UV radiation
