1. A system for real-time monitoring of plant status comprising:
a probe comprising:
a body that attaches to the plant; and
a microprobe comprising a conductive gallium nitride tip that has been grown on top of a silicon needle body; and
a device that receives the impedance measurements from the microprobe and provides information to a user based on the impedance measurements.
