Emisense Announces Commercialization of Next Generation Particulate Matter Sensor

Emisense Technologies 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.

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.

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.
