Plants are very common in our world and and contain a vast amount of information. Although there are open debates about the intelligence of plants, it is undeniable that plants have a great ablity to do low-cost sensing and rudimentary communication. The electrophysiology of plants has sparked interest since the late 1800s, but this topic has not been explored recently in the context of modern information technology. We are building novel electronic sensors that "take a peek" inside the biological activity of living plants, and explore their use as sensors and thought-provoking educational tools for children and museum exhibits.
