California-based SirenOpt is developing PlasmaSens, a manufacturing intelligence system that pairs cold atmospheric plasma sensing with machine-learning analytics to detect defects and material inconsistencies in real time. The platform integrates into both roll-to-roll and piece-to-piece production lines, providing micron-level resolution and actionable feedback that can boost yields, cut waste, and shorten product-development cycles. Initial target markets include battery electrode fabrication, aerospace composites, semiconductors, power-generation components, and automotive parts. The company has seen strong early interest from blue-chip customers and plans to complete its first full inline factory deployments in 2026. To speed commercialization, SirenOpt is expanding its engineering, product, and commercial teams and broadening pilot programs across the US, Europe, and Asia. Financially, the firm just secured a $6.5 million equity round and recently won a $2.4 million grant from the California Energy Commission to tailor PlasmaSens for battery-electrode manufacturing.
