Flexible microsensor array for monitoring dissolved oxygen and water content in the plant root zone
"Control of water and oxygen (O₂) in the root zone is vital to support plant growth in the microgravity environment. The ability to control these sometimes opposing parameters in the root-zone is dependent upon the availability of sensors to detect these elements and provide feedback for control systems. In the present study we demonstrate the feasibility of using microsensor arrays on a flexible substrate for dissolved O₂ detection with two representative plant growth systems: a porous tube (PT) system and a substrate-based system. Additionally, we demonstrate using a conductivity-based 4-point microprobe (FPM) for wetness detection in both the plant growth systems."--Abstract, leaf iii.
