As we all know, great progress has been made in medical technology for humans. We often see TV documentaries and medical dramas such as "ER" that show EKG wires attached to patients. But did you know the same technology is being applied to plants?

A "leaf sensor" is a device that measures water loss or stress in plants by monitoring the moisture level in plant leaves. The first leaf sensor was developed by an Israeli company that was granted a US patent for a mechanical leaf thickness sensing device in 2001. This company has made progress using their leaf sensory technology in fruit orchards in Israel. A solid state smart leaf sensor technology was developed by the University of Colorado at Boulder for NASA in 2007. It was designed to help monitor and control agricultural water demand.
Leaf sensor technology has the potential to save between 30% and 50% of irrigation water by reducing irrigation from once every 24 hours to about every 2 to 2.5 days by sensing water deficit stress. Leaf sensor technology indicates water deficit stress by measuring the water pressure of a leaf, which decreases dramatically at the beginning of leaf dehydration. Early detection of impending water deficit stress in plants can be used as an input parameter for precision irrigation control by allowing plants to communicate water requirements directly to humans and/or electronic interfaces. For example, a base system utilizing the wirelessly transmitted information of several sensors appropriately distributed over various sectors of a round field irrigated by a center-pivot irrigation system could tell the irrigation lever exactly when and what field sector needs to be irrigated.
Wow, what's next? Talking plants?!
