A team of researchers at Penn State's College of Agricultural Sciences is working on plant-based sensors that clip onto individual plants, tracking the thickness and electrical capacitance of their leaves, a technique that could be useful in promoting water-use efficiency.

With a precise tracking system like this, farmers can continuously monitor water stress in fields and avoid both under-watering and overwatering the crops, writes

Researchers believe the system can be integrated in modern agriculture in such a way that the real time information passed on by leaf sensors will activate or deactivate the irrigation system, notes Science Daily
