A Real Time Continuous Chemical and Biological Sensor Platform

A REAL TIME CONTINUOUS CHEMICAL AND BIOLOGICAL SENSOR PLATFORM

Economic, InSitu Measurement Tool

Lumense’s sensor platform supports, for the first time, an ability to measure, affordably and in near real-time, in situ chemical and microbial concentrations. It can serve as a powerful tool for optimizing industrial and agricultural production processes as well as understanding and solving global environmental and sustainability challenges, including those involving air and water quality, food safety, and the health of natural resources. Key pieces of information needed in the struggle toward sustainability are the current condition of a resource or environment, the true composition of process raw materials, finished goods, and waste streams, and the amount of load being placed on an environment by process outputs (i.e. pollutants).

A REAL TIME CONTINUOUS CHEMICAL AND BIOLOGICAL SENSOR PLATFORM

Since processes and environments are highly dynamic, this information must be timely and abundant, or cause-to-effect ties will be lost.

Lemense sensor plaform determines, continuously and almost immediately, how much of a “target-of-interest” is present. It uses optical interferometry to detect the way a chemical or biological target in a flow of liquid (like water) or gas (like air) changes the optical properties of a coating on a glass waveguide. The glass waveguide is small, about two square centimeters in size, and is made in a semiconductor foundry like most electronic circuits. It can be made to include multiple interferometers. Each interferometer, if covered with a different coating, is effectively a separate sensor, and there can be far more than four on a waveguide.

The current market for chemical and biological sensors, sampling tools, and analyzers exceeds $5 billion, but is highly fragmented by application and technology. Lumense aims to revolutionize this market, and to grow it substantially, partly by standardizing it.

Target markets include scores of industrial and agricultural monitoring applications, water quality monitoring, indoor and outdoor air quality monitoring, military and homeland security, law enforcement, medical diagnostics, and public safety.
