Emisense Announces Commercialization of Next Generation Particulate Matter Sensor

LADERA RANCH, Calif., March 7, 2025 /PRNewswire/ -- Emisense Technologies, LLC today announced an agreement to commercialize next-generation sensors for particulate matter (PM) with a global Tier-1 Automotive Supplier. The agreement combines the Emisense electrostatic PM (ePM) sensor technology with the industrialization capabilities of a proven leader in global automotive sensor manufacturing.

"This agreement marks the next chapter for ePM technology," states Patrick Thompson, Emisense CEO. "After almost 2 years of technical evaluations by the USCAR consortium, ePM technology has been selected as the most promising for meeting future OBD requirements. We are excited to have a world class partner to advance both development and commercialization for the next generation of near-zero-emissions trucks and cars."

"It's clear that even as the world continues to de-carbonize, customers are still demanding innovation and advancement in clean and efficient combustion," continues Mr. Thompson. "As long as internal combustion has a role to play in the larger mobility picture, the key is to ensure such engines are as close to zero emissions as possible, and this is where ePM sensors come in."

The ePM technology is ideal for end-of-tailpipe applications, enabling easier compliance with on board diagnostic (OBD) requirements that are tightening in the coming years. Key advantages include faster response times, superior sensitivity, and a continuous signal which avoids the complex models required to predict periodic sensor response with existing resistive PM sensors.

"As an industry, we've made good progress delivering huge reductions in the types of pollutants targeted by the Clean Air Act," states Mr. Thompson. "However, the only pollutant that is still rising in cars and trucks is ultrafine PM, or soot, which has negative impacts on human health that are near term and well understood. PM filters are proven solutions, and next-generation PM sensors are required to ensure filters are operating properly for the life of the vehicle."

Advantages of the new Electrostatic ePM sensors (also known under the trade name of PMTrac^®) are expected to include lower compliance costs from easier OBD system integration; sensor self-diagnostics with tamper detection capability; and lower warranty costs. Sample availability is starting in 2025, with production planned to start in 2028.

"Now that we have initial adoption in automotive, and a strong Tier-1 supplier partner," continues Mr. Thompson, "we are eager to support evaluation and adoption in other segments and geographies. For example, applications exist for continuous monitoring of PM and particle number (PN) in gasoline direct injected (GDI) engines; oil & gas pipeline compressors; marine, such as boats and barges in ports and inland waterways; stationary, such as backup generators for data centers and hospitals; transportation refrigeration units (TRUs); and non-road applications like agriculture, mining, forestry, and construction."
