\## Executive Summary

Researchers have developed an innovative, low-cost system for monitoring photosynthesis in plants, which could transform how plant health is assessed and managed in various settings. Traditional methods for measuring photosynthesis are prohibitively expensive, with instruments ranging from $42,000 to $89,000, making them inaccessible for many researchers and limiting long-term studies across multiple leaves. This new approach offers a solution.

The system consists of small, autonomous chambers that attach to individual leaves. Each chamber is built using inexpensive materials, including a 3D-printed clamp and a thermoformed dome, and costs roughly $62. These chambers are designed to periodically close, measure carbon dioxide (CO2) drawdown, and then reopen to refresh the air, allowing for continuous monitoring without the need for complex equipment like pumps or gas tubing. This simplicity enables researchers to monitor multiple leaves simultaneously, providing a broader view of plant health.

To validate the effectiveness of this system, the researchers compared its measurements with those from a high-end gas exchange instrument called the CIRAS-4 over 29 testing sessions. The results showed a strong correlation (R² = 0.90), indicating that the low-cost chambers can reliably capture photosynthesis data.

The research also demonstrated the system's versatility by successfully monitoring both C3 and CAM photosynthesis plants and adapting to various leaf shapes. In a nine-day field test, six chambers monitored different leaves of the same plant during drought and rewatering phases. The data revealed distinct nighttime CO2 uptake and recovery patterns for each leaf, insights that would be lost with conventional whole-plant measurement methods.

This development has significant implications for plant science, education, and agriculture. By making photosynthesis monitoring more accessible, researchers and educators can better study plant responses to environmental changes and stressors. In agriculture, farmers could use this technology to optimize crop management practices based on detailed, real-time data from individual plants, potentially leading to improved yields and resource efficiency.

While the results are based on controlled validations and simulations, the potential for real-world applications is evident. This system could empower a wider range of users, from academic researchers to agricultural practitioners, to engage in detailed plant health assessments with a level of granularity that was previously unattainable.

\## Academic Abstract

Photosynthesis is a direct biomarker of plant health and functioning. However, measuring net photosynthesis on individual leaves requires expensive (USD 42,000 - USD 89,000) instruments and manual effort. This limits access to photosynthesis sensing and makes long-term monitoring across multiple leaves difficult. We present a 1000x low-cost, autonomous sensing system that enables longitudinal monitoring of photosynthesis on living leaves over multiple days. Guided by a formative user study with 13 plant biology researchers, the system integrates an automated, leaf-attached chamber with a low-cost CO2 sensor. Built using a 3D-printed clamp and thermoformed dome, the chamber periodically closes to measure CO2 drawdown and reopens to refresh the air. Each chamber costs about USD 62 and operates independently, allowing multiple leaves to be monitored simultaneously without pumps or gas tubing. We characterize each chamber and validate its measurements against a research-grade gas exchange instrument (CIRAS-4) across 29 sessions (R^2 = 0.90). We also demonstrate monitoring of C3 and CAM photosynthesis plants, adaptability to different leaf geometries, and a light-response experiment. In a nine-day deployment, six chambers captured simultaneous CO2 exchange from individual leaves of the same plant during drought and rewatering. Each leaf showed different patterns of nighttime CO2 uptake and recovery, which a whole-plant CO2 measurement instrument would obscure. To our knowledge, this is the first demonstration of such leaf-level photosynthesis dynamics using independent, low-cost autonomous chambers. Our work opens new opportunities for plant science, education, and data-driven agriculture.
