Science Basics
Understand the biological principles behind Babbeleaf's signal sensing and interpretation. Explore plant electrophysiology, response mechanisms, and real-world use cases.
What Signals Do Plants Produce?
Plants generate low-voltage bioelectrical signals in response to internal and external stimuli. These signals, known as action potentials or variation potentials, can be detected on the surface of leaves or stems using non-invasive electrodes.
How Babbeleaf Detects Signals
Babbeleaf uses high-impedance analog inputs and software-based filtering to measure microvolt-level fluctuations in plant voltage. These signals are then transformed into both visual waveforms and audio output, allowing you to listen to and observe living electrical behavior.
Why It Matters
- Scientific Discovery: Reveal plant stress responses, hydration patterns, and circadian rhythms.
- Classroom Learning: Teach plant biology, electricity, and digital signal processing in an interactive format.
- Experimental Gardening: Record plant responses to touch, light, sound, and water in real time.
Recommended Materials
- Electrodes (silver/silver chloride pads or plant-safe clips)
- Standard houseplants (pothos, spider plant, peace lily)
- Light source, fan, or temperature change (for stimulus testing)
Babbeleaf is not a diagnostic instrument, but a powerful educational and observational tool. Its insights are qualitative, real-time, and always alive.
