Using plants as antennae | Plantenna Blog #9
Using a plant to increase the radiation efficiency of an antenna, it seemed like science fiction until recently. However, a simulation study including an Antenna Booster, a simple printed circuit board (PCB) and a basic leaf model showed that the use of the plant itself as an antenna might actually be closer to reality than we think.

Plants as organic river cleaners | Plantenna Blog #3
As hydrologists we are interested in the interaction between plans and the water cycle. We traditionally look at plant transpiration, the interception of precipitation by leaves, or detection vegetation water stress. However, new global environmental challenges also come with new roles for plants.
