The Electro Particle Analyzer is a novel scientific instrument designed to simultaneously measure three critical properties of aerosol particles — aerodynamic diameter and mass — under atmospheric conditions. A single device capable of doing this in the field would represent a significant advance for atmospheric science, air quality monitoring, and climate research.

The project's goal is to develop a functional prototype for research purposes. The instrument's core challenge is engineering precision measurement systems small enough to integrate into a single handheld-scale device while maintaining accuracy across all measurement modalities.

Luminosity assembled an interdisciplinary team of graduate and undergraduate student researchers spanning Electrical Engineering, Computer Science, Physics, and Aerospace to research and develop the project over a 14-month timeline. The work spans custom PCB design, analog electronics, fluid dynamics modeling, and rapid prototyping of the physical housing — visible in the progression from CAD model to 3D-printed prototype to populated circuit board.

The project was funded by a philanthropic gift, reflecting strong external confidence in both the technical approach and the team's ability to deliver a commercializable prototype.
