What ACEINNA does
ACEINNA, Inc. is a MEMS-based sensing solutions company headquartered in Tewksbury, Massachusetts, that designs and manufactures current sensors, inertial measurement units (IMUs), inertial navigation systems (INS), and flow/pressure sensors for automotive, industrial, and autonomous vehicle markets. The company was spun off from MEMSIC, Inc. in 2017 by founder Dr. Yang Zhao and is venture-backed by IDG Capital. ACEINNA's product portfolio is organized around three technology pillars: (1) Anisotropic Magnetoresistance (AMR/xMR) based current sensor ICs (MCx1101 industrial and MCx2101 AEC-Q100 automotive families) delivering 5MHz bandwidth and 80ns response time for SiC/GaN wide-bandgap power conversion; (2) open-source inertial measurement and navigation platforms (OpenIMU, IMU330RA, INS401) with triple-redundant MEMS sensor architecture, ASIL-B functional safety certification, and centimeter-level RTK positioning; and (3) patented thermal MEMS flow and differential pressure sensors (MFC2030, MDP200) for medical, HVAC, and process control applications.
ACEINNA generates revenue primarily through hardware sales of sensor ICs and modules, distributed via a multi-tier global channel including Avnet (Flagship partner), Richardson Electronics, WPG Americas, Mouser, Digi-Key, and regional representatives across North America, EMEA, APAC, and South America. Pricing is quote-based for volume production, with reference points including OpenIMU developer kits at $395, OpenIMU300 production modules under $100, and INS401 INS modules under $500—a deliberate down-market pricing strategy relative to typical $10K+ INS systems. Manufacturing is handled by the company's wholly-owned Chinese subsidiary, ACEINNA Transducer Systems Co. Ltd. in Wuxi, which holds ISO 9001 and IATF 16949 certifications. The company maintains R&D and sales offices in Andover MA, San Jose CA, and Naperville IL, and targets automotive power conversion (EV/hybrid OEMs and Tier 1s), ADAS/AV developers, industrial power and datacenter customers, construction and agriculture OEMs, and an open-source developer community served through GitHub, VS Code extensions, and IEEE webinars.

ACEINNA competitors and assessment
Company assessmentBroad incumbents
- Analog Devices: Analog Devices is a broad mixed-signal and sensor incumbent, with heritage in MEMS (where Dr. Yang Zhao and several ACEINNA VPs previously worked) and current-sensing signal chains. It overlaps ACEINNA in high-performance IMUs and isolated current sensing at the high end, with a much broader portfolio.
- STMicroelectronics: STMicroelectronics is a broad semiconductor incumbent with a significant MEMS IMU franchise (LSM6DS family) and a major automotive power/SiC business, overlapping ACEINNA in both IMU and automotive-grade current sensing for power conversion.
- Honeywell Aerospace: Honeywell Aerospace is a broad incumbent in high-performance INS and inertial sensors for commercial aviation, defense, and increasingly urban air mobility, with MEMS-based HG1930-class products overlapping ACEINNA's heritage in MEMSIC's aircraft INS deployments.
